[PATCH 0/6] Fixup Cirrus SX control usage
by Charles Keepax 03 Jun '22

03 Jun '22

Mostly the usage of the SX controls seems to match the lowest gain value + number of gain levels expected. The one notable exception there being cs53l30 as David noted. However, there are a couple of other places where the minimum value/TLVs are slightly incorrectly specified. There are two I couldn't quite work out yet, any input on these greatly appreciated: SOC_DOUBLE_R_SX_TLV("Speaker Volume", CS42L52_SPKA_VOL, CS42L52_SPKB_VOL, 0, 0x40, 0xC0, hl_tlv), 0.5dB step 0x40 - -96dB 0x00 - 0dB This one is weird, the datasheet says 0x40 is the minimum, which matches, but the datasheet also says 0.5dB steps to 0x00 being 0dB which doesn't match with 0x40 being the minimum, or 0xC0 being the number of levels. Some clarification will needed from the hardware guys. SOC_SINGLE_SX_TLV("Beep Volume", CS42L56_BEEP_FREQ_OFFTIME, 0, 0x07, 0x23, beep_tlv), 2dB step 0x07 - -50dB 0x00 - 0dB 0x06 - +6dB The minimum checks out at 0x07, but rest of this is weird. The values in the datasheet don't make sense, based on starting at -50dB with a 2dB step, 0x06 should equate to 12dB, over 31 volume levels, not 6dB over 35 volume levels as stated. The control specifies 0x23(35) levels, which takes us up to a final value of 0x0A at 20dB. Again some clarification from the hardware guys might be needed here. Finally it is worth noting I don't actually have hardware for most of these devices, so mostly this is just build tested.

[PATCH v2] ASoC: Intel: cirrus-common: fix incorrect channel mapping
by Brent Lu 03 Jun '22

03 Jun '22

From: xliu <xiang.liu(a)cirrus.com> The default mapping of ASPRX1 (DAC source) is slot 0. Change the slot mapping of right amplifiers (WR and TR) to slot 1 to receive right channel data. Also update the ACPI instance ID mapping according to HW configuration.

Issues with ALSA after update to Pop!_OS 22.04 LTS Jaunty Pipewire
by Mikhail Kravchenko 03 Jun '22

03 Jun '22

I updated the operating system running on my machine to 22.04 Jaunty. This update brings the system over to pipe-wire. After running certain programs that utilize alsa, the audio on my system becomes intermittent and runs only one application's audio at a time. Resetting the pipe-wire services and forcing alsa to reload its modules does not reliably mitigate the issue. This is the url generated by alsa-info. http://alsa-project.org/db/?f=4d643a3153ffabd5c72313e8ffa3c9f393e676ef On a power cycle, the audio seems to work fine, but as soon as I run the problematic program I get the output: ALSA lib pcm_dmix.c:1032:(snd_pcm_dmix_open) unable to open slave If the program's audio is successful, and it opens the slave. Audio to other applications is upset. sudo alsa force-reload Unloading ALSA sound driver modules: snd-seq-dummy snd-seq-midi snd-seq-midi-event snd-hda-codec-realtek snd-hda-codec-generic snd-hda-codec-hdmi snd-hda-intel snd-intel-dspcfg snd-intel-sdw-acpi snd-hda-codec snd-hda-core snd-hrtimer snd-usb-audio snd-usbmidi-lib snd-hwdep snd-rawmidi snd-seq snd-pcm snd-seq-device snd-timer (failed: modules still loaded: snd-hda-codec-realtek snd-hda-codec-generic snd-hda-codec-hdmi snd-hda-intel snd-intel-dspcfg snd-intel-sdw-acpi snd-hda-codec snd-hda-core snd-hrtimer snd-usb-audio snd-usbmidi-lib snd-hwdep snd-rawmidi snd-seq snd-pcm snd-seq-device snd-timer).

USB-Audio: Steinberg UR44 not getting expected results

alsa-project/alsa-ucm-conf issue #163 was opened from CameronNemo: I am testing the following software: * alsa-lib: 1.2.7 * alsa-utils: 1.2.7 * alsa-ucm-conf: 1.2.7 Unfortunately the changes for the Steinberg UR44 do not seem to be working as intended. I am not seeing the expected mono inputs and stereo outputs that I see defined in `/usr/share/alsa/ucm2/USB-Audio/Steinberg/UR44-HiFi.conf`. I am seeing the following from `aplay -L`: ``` null Discard all samples (playback) or generate zero samples (capture) default Default Audio Device sysdefault Default Audio Device default:CARD=UR44

[PATCH 0/4] hwdep: define interface for hwdep device
by GitHub pull_request - edited 02 Jun '22

02 Jun '22

alsa-project/alsa-gobject pull request #73 was edited from takaswie: The protocol in ALSA HwDep character device has common feature to each device. It's suitable for userspace implementation to have GObject interface for such features. This patchset adds the interface. The implementation of interface should have four methods; open, get_protocol_version, get_device_info, and create_source. Additionally, it should emit handle-disconnection signal when detecting ENODEV error in the interation of source. It requires to notify userspace application since the application should release character device immediately. ``` Takashi Sakamoto (4): hwdep: use explicit value for iface type enumeration hwdep: device-common: add interface for common feature of ALSA HwDep device hwdep: add error domain for implementators of DeviceCommon interface hwdep: device-info: allow to set property at instantiation src/hwdep/alsahwdep-enum-types.h | 89 +++++++++------- src/hwdep/alsahwdep.h | 2 + src/hwdep/alsahwdep.map | 10 ++ src/hwdep/device-common.c | 178 +++++++++++++++++++++++++++++++ src/hwdep/device-common.h | 106 ++++++++++++++++++ src/hwdep/device-info.c | 38 ++++++- src/hwdep/meson.build | 2 + tests/alsahwdep-enums | 10 ++ 8 files changed, 389 insertions(+), 46 deletions(-) create mode 100644 src/hwdep/device-common.c create mode 100644 src/hwdep/device-common.h ``` Request URL : https://github.com/alsa-project/alsa-gobject/pull/73 Patch URL : https://github.com/alsa-project/alsa-gobject/pull/73.patch Repository URL: https://github.com/alsa-project/alsa-gobject
