[PATCH] ALSA: usb-audio: Drop bogus dB range in too low level
by Takashi Iwai 27 Feb '21

27 Feb '21

Some USB audio firmware seem to report broken dB values for the volume controls, and this screws up applications like PulseAudio who blindly trusts the given data. For example, Edifier G2000 reports a PCM volume from -128dB to -127dB, and this results in barely inaudible sound. This patch adds a sort of sanity check at parsing the dB values in USB-audio driver and disables the dB reporting if the range looks bogus. Here, we assume -96dB as the bottom line of the max dB. Note that, if one can figure out that proper dB range later, it can be patched in the mixer maps.

[PATCH] alsa-tools/hdspmixer: enhance preset save and add hardware ouput loopback buttons
by fassl 27 Feb '21

>From 3c887b31fa57ca3004c2eaf0ee5abc0b3f94da70 Mon Sep 17 00:00:00 2001 From: Jasmin Fazlic <superfassl(a)gmail.com> Date: Thu, 4 Feb 2021 15:58:33 +0100 Subject: [PATCH 1/2] alsa-tools/hdspmixer: enhance saving of presets Changing the version in the file header would make a preset file not readable by older versions of the tool. If we just append new data always at the end of the save procedure we should have no problems reading them with different versions, as they all just read to a certain point and ignore the rest of the file. This patch implements the logic to save the presets first to a file called file_name.tmp and appends any extra data that would come after in a possibly present file_name file. Any data written by newer versions would remain in the preset file and from now on no old version should remove data written by newer versions. Also since we write to a temporary file and rename afterwards an extra feature is gained of not corrupting the preset should we crash.

Efforts were made to hide the buttons for not yet enabled devices but due to difficulties in implementation was cancelled for the time being. Should it be a no-go efforts should be made to fix this and hide them, although I would think fixing the driver for other devices would be an effort with much more merit. This is currently only enabled for HDSP9632 devices with following driver patch: https://github.com/tiwai/sound/commit/da2a040ee7cfe1dd57d5bec7906cb979c5787… Signed-off-by: Jasmin Fazlic <superfassl(a)gmail.com> --- hdspmixer/pixmaps/loopback.xpm | 69 ++++ hdspmixer/pixmaps/output.xpm | 498 +++++++++++++++----------- hdspmixer/pixmaps/output_r.xpm | 498 +++++++++++++++----------- hdspmixer/src/HDSPMixerCard.cxx | 34 ++ hdspmixer/src/HDSPMixerCard.h | 2 + hdspmixer/src/HDSPMixerLoopback.cxx | 133 +++++++ hdspmixer/src/HDSPMixerLoopback.h | 48 +++ hdspmixer/src/HDSPMixerOutput.cxx | 1 + hdspmixer/src/HDSPMixerOutput.h | 3 + hdspmixer/src/HDSPMixerOutputData.h | 1 + hdspmixer/src/HDSPMixerOutputs.cxx | 4 +- hdspmixer/src/HDSPMixerPresetData.cxx | 1 + hdspmixer/src/HDSPMixerPresetData.h | 1 + hdspmixer/src/HDSPMixerPresets.cxx | 2 + hdspmixer/src/HDSPMixerWindow.cxx | 68 ++++ hdspmixer/src/Makefile.am | 2 + hdspmixer/src/defines.h | 2 +- hdspmixer/src/pixmaps.cxx | 1 + hdspmixer/src/pixmaps.h | 1 + 19 files changed, 931 insertions(+), 438 deletions(-) create mode 100644 hdspmixer/pixmaps/loopback.xpm create mode 100644 hdspmixer/src/HDSPMixerLoopback.cxx create mode 100644 hdspmixer/src/HDSPMixerLoopback.h diff --git a/hdspmixer/pixmaps/loopback.xpm b/hdspmixer/pixmaps/loopback.xpm new file mode 100644 index 0000000..a327467 --- /dev/null +++ b/hdspmixer/pixmaps/loopback.xpm @@ -0,0 +1,69 @@ +/* XPM */ +char const * loopback_xpm[] = { +"34 15 51 1", +" c None", +". c #2E3038", +"+ c #FFFB7C", +"@ c #FDF97B", +"# c #2E2D11", +"$ c #000000", +"% c #383716", +"& c #898740", +"* c #F1EE75", +"= c #22210A", +"- c #727034", +"; c #E2DE6D", +"> c #D5D267", +", c #787637", +"' c #FBF77A", +") c #AAA750", +"! c #ABA851", +"~ c #CDC962", +"{ c #83813C", +"] c #C8C560", +"^ c #84823D", +"/ c #F7F378", +"( c #949145", +"_ c #B7B457", +": c #949245", +"< c #353414", +"[ c #87853F", +"} c #F1ED75", +"| c #3B3A17", +"1 c #DFDB6C", +"2 c #161505", +"3 c #4B4A20", +"4 c #E5E16E", +"5 c #FEFA7C", +"6 c #E8E470", +"7 c #535124", +"8 c #FAF679", +"9 c #E7E370", +"0 c #66642E", +"a c #E4E06E", +"b c #F6F277", +"c c #EAE671", +"d c #E0DC6C", +"e c #B9B658", +"f c #5F5D2A", +"g c #EDE973", +"h c #69672F", +"i c #DDD96A", +"j c #333342", +"k c #32323E", +"l c #313136", +"..................................", +".++++++++++++++++++++++++++++++++.", +".++++++++++++++++++++++++++++++++.", +".++++++++++++++++++++++++++++++++.", +".+++@#++++@$$%&*@$$=-;+@#++>,*+++.", +".+++@#++++@#+')!@#+@~{+@#+]^/++++.", +".+++@#++++@#+'!!@#+@~(+@#_:'+++++.", +".+++@#++++@$$<[}@$$$|1+@234++++++.", +".+++@#++++@#++++@#+5678@#90a+++++.", +".+++@#++++@#++++@#+59#b@#+c0d++++.", +".+++@$$$$e@#++++@$$2f]+@#++ghi+++.", +".++++++++++++++++++++++++++++++++.", +".++++++++++++++++++++++++++++++++.", +".++++++++++++++++++++++++++++++++.", +"..jklllllllllkj....jklllllllllkj.."}; diff --git a/hdspmixer/pixmaps/output.xpm b/hdspmixer/pixmaps/output.xpm index 8f7cd65..c827b1c 100644 --- a/hdspmixer/pixmaps/output.xpm +++ b/hdspmixer/pixmaps/output.xpm @@ -1,220 +1,282 @@ /* XPM */ char const * output_xpm[] = { -"36 208 9 1", -" c #595966", -". c #2E3038", -"+ c #000000", -"@ c #474951", -"# c #404044", -"$ c #7A7A8F", -"% c #27272B", -"& c #616176", -"* c #737384", -" ", -" ..................................

[PATCH] ALSA: usb-audio: Don't abort even if the clock rate differs
by Takashi Iwai 27 Feb '21

27 Feb '21

The commit 93db51d06b32 ("ALSA: usb-audio: Check valid altsetting at parsing rates for UAC2/3") changed the behavior of the function set_sample_rate_v2v3() slightly to treat the inconsistent sample rate as an error. It was done by assumption that the sample rate validation should have been done at the parser phase as implemented in that patch. But the validation is later selectively enabled only for certain devices as it causes a regression (the commit fe773b8711e3 "ALSA: usb-audio: workaround for iface reset issue"), and now the inconsistency surfaced as a fatal error while it worked in the past as is, as reported for FiiO M3K DAC. For recovering from the regression, change set_sample_rate_v2v3() again to ignore the sample rate difference as non-error.

[PATCH v5 0/9] ALSA: add virtio sound driver
by Anton Yakovlev 27 Feb '21

27 Feb '21

This series implements a driver part of the virtio sound device specification v8 [1]. The driver supports PCM playback and capture substreams, jack and channel map controls. A message-based transport is used to write/read PCM frames to/from a device. As a device part was used OpenSynergy proprietary implementation. v5 changes: - Fixed another bunch of sparse warnings (replaced virtio_cread() -> virtio_cread_le()), no functional changes. (Sorry, I didn't know how to run sparse locally, now everything should be fixed) [1] https://lists.oasis-open.org/archives/virtio-dev/202003/msg00185.html Anton Yakovlev (9): uapi: virtio_ids: add a sound device type ID from OASIS spec ALSA: virtio: add virtio sound driver ALSA: virtio: handling control messages ALSA: virtio: build PCM devices and substream hardware descriptors ALSA: virtio: handling control and I/O messages for the PCM device ALSA: virtio: PCM substream operators ALSA: virtio: introduce jack support ALSA: virtio: introduce PCM channel map support ALSA: virtio: introduce device suspend/resume support MAINTAINERS | 9 + include/uapi/linux/virtio_ids.h | 1 + include/uapi/linux/virtio_snd.h | 334 +++++++++++++++++++++ sound/Kconfig | 2 + sound/Makefile | 3 +- sound/virtio/Kconfig | 10 + sound/virtio/Makefile | 13 + sound/virtio/virtio_card.c | 462 +++++++++++++++++++++++++++++ sound/virtio/virtio_card.h | 113 ++++++++ sound/virtio/virtio_chmap.c | 219 ++++++++++++++ sound/virtio/virtio_ctl_msg.c | 310 ++++++++++++++++++++ sound/virtio/virtio_ctl_msg.h | 78 +++++ sound/virtio/virtio_jack.c | 233 +++++++++++++++ sound/virtio/virtio_pcm.c | 498 ++++++++++++++++++++++++++++++++ sound/virtio/virtio_pcm.h | 120 ++++++++ sound/virtio/virtio_pcm_msg.c | 392 +++++++++++++++++++++++++ sound/virtio/virtio_pcm_ops.c | 491 +++++++++++++++++++++++++++++++ 17 files changed, 3287 insertions(+), 1 deletion(-) create mode 100644 include/uapi/linux/virtio_snd.h create mode 100644 sound/virtio/Kconfig create mode 100644 sound/virtio/Makefile create mode 100644 sound/virtio/virtio_card.c create mode 100644 sound/virtio/virtio_card.h create mode 100644 sound/virtio/virtio_chmap.c create mode 100644 sound/virtio/virtio_ctl_msg.c create mode 100644 sound/virtio/virtio_ctl_msg.h create mode 100644 sound/virtio/virtio_jack.c create mode 100644 sound/virtio/virtio_pcm.c create mode 100644 sound/virtio/virtio_pcm.h create mode 100644 sound/virtio/virtio_pcm_msg.c create mode 100644 sound/virtio/virtio_pcm_ops.c -- 2.30.0

ASoc: soc_core.c stream direction from snd_soc_dai
by Matt Flax 26 Feb '21

26 Feb '21

Hi there, A large number of audio codecs allow different formats for playback and capture. This becomes very useful when there are different latencies between playback and capture hardware data lines. For example digital isolation chips typically have a 1 bit delay in propagation as the bit clock rate gets faster for higher sample rates. By setting the capture and playback formats to differ by one or two bit clock cycles, the delay problem is solved. There doesn't seem to be a simple way to detect stream direction in the codec driver's set_fmt function. The snd_soc_runtime_set_dai_fmt function : https://github.com/torvalds/linux/blob/master/sound/soc/soc-core.c#L1480 calls the snd_soc_dai_set_fmt function : https://github.com/torvalds/linux/blob/master/sound/soc/soc-dai.c#L101 which calls the set_fmt function : https://github.com/torvalds/linux/blob/master/include/sound/soc-dai.h#L189 The snd_soc_dai_ops set_fmt function is defined as : int (*set_fmt)(struct snd_soc_dai *dai, unsigned int fmt); Is there a simple way to find the stream direction from a snd_soc_dai ? If the stream direction can be detected then the playback and capture formats can be set independently for the codec. It there a different way to set the playback and capture formats for the codec independently at runtime, depending on the sample rate ? Matt

by Hans de Goede 26 Feb '21

26 Feb '21

Hi All, Here is a patch series consisting of some codecs/rt5640 cleanups and addition of HW volume control support to the rt5640 .conf snippets. Note patch 7 and 8 depend on a new "aif:%d" part being added to the components string, the kernel patches for this are pending upstream in the "[PATCH 0/5] AsoC: rt5640/rt5651: Volume control fixes" patch series. Patches 7 and 8 should probably not be merged until the kernel patches have landed, because theoretically the new component string part could change as part of the review of the kernel patches. Regards, Hans Hans de Goede (8): codecs/rt5640: Cleanup: unify Stereo / Mono ADC handling codecs/rt5640: Cleanup: Initially disable all inputs and outputs codecs/rt5640: Cleanup: Move 'SPK MIX' setup to main EnableSequene codecs/rt5640: Drop bogus 'DIG MIXL DAC L2 Switch' setting codecs/rt5640: Unify capture volume for AIF1 and AIF2 recording paths codecs/rt5640: Add hardware volume-control support codecs/rt5640: Use the new "aif:%d" part of the components string codecs/rt5640: Specify Playback/CaptureMasterElem for HW volume-control ucm2/bytcr-rt5640/HiFi.conf | 46 +++++++++++++++++ ucm2/codecs/rt5640/DigitalMics.conf | 18 ++++++- ucm2/codecs/rt5640/EnableSeq-AIF-unknown.conf | 7 +++ ucm2/codecs/rt5640/EnableSeq-AIF1.conf | 7 +++ ucm2/codecs/rt5640/EnableSeq-AIF2.conf | 7 +++ ucm2/codecs/rt5640/EnableSeq.conf | 50 ++++++++++++++----- ucm2/codecs/rt5640/HeadPhones.conf | 15 +++++- ucm2/codecs/rt5640/HeadsetMic.conf | 24 ++++++--- ucm2/codecs/rt5640/IN1-InternalMic.conf | 27 ++++++---- ucm2/codecs/rt5640/IN3-InternalMic.conf | 27 ++++++---- ucm2/codecs/rt5640/MonoSpeaker.conf | 17 +++++-- ucm2/codecs/rt5640/Speaker.conf | 17 +++++-- 12 files changed, 211 insertions(+), 51 deletions(-) create mode 100644 ucm2/codecs/rt5640/EnableSeq-AIF-unknown.conf create mode 100644 ucm2/codecs/rt5640/EnableSeq-AIF1.conf create mode 100644 ucm2/codecs/rt5640/EnableSeq-AIF2.conf -- 2.30.1

Possible alsa bug around USB drivers
by Steven Skeard 25 Feb '21

25 Feb '21

Hey all, The last few weeks I've been plagued by inconsistent audio on my PopOS 20.10 desktop. Sometimes on boot everything would be fine, but other times I would have no working audio and only dummy devices in the audio menus. I eventually found that if I specify the modprobe order so that the USB driver (eg. for my webcam) loads after the onboard motherboard driver, that audio will work consistently. Here are the related links: - Reddit thread where I posted the original problem and the solution: https://www.reddit.com/r/pop_os/comments/lmvbj3/audio_not_working_after_upg… - A related thread where it sounds like an arch user has the same problem: https://bbs.archlinux.org/viewtopic.php?id=260373 - The alsa info I uploaded while under the effects of the problem: http://alsa-project.org/db/?f=a23ccbb818fec6eaf08b032504eac5d5d8a30589 I'm not really sure where this problem originated but I figured you guys might be able to point me in the right direction if it is not an alsa problem. I don't think I messed with the original alsa-base.conf but I suppose my memory could be failing me here. I'm not sure where this file comes from but I'm guessing it could be either a pop os, ubuntu, or alsa default configuration? Thanks, Steven Skeard

[PATCH] ASoC: Intel: bytcr_rt5640: Fix HP Pavilion x2 10-p0XX OVCD current threshold
by Hans de Goede 25 Feb '21

25 Feb '21

When I added the quirk for the "HP Pavilion x2 10-p0XX" I copied the byt_rt5640_quirk_table[] entry for the HP Pavilion x2 10-k0XX / 10-n0XX models since these use almost the same settings. While doing this I accidentally also copied and kept the non-standard OVCD_TH_1500UA setting used on those models. This too low threshold is causing headsets to often be seen as headphones (without a headset-mic) and when correctly identified it is causing ghost play/pause button-presses to get detected. Correct the HP Pavilion x2 10-p0XX quirk to use the default OVCD_TH_2000UA setting, fixing these problems.
