[PATCH 0/3] ALSA: usb-audio: Reduce device table
by Takashi Iwai 23 Aug '20

23 Aug '20

Hi, this is a patch set for USB-audio driver to reduce the unnecessary entries from the exported device table. Also it contains the corrections of the device matching for a few entries to be more strict.

[PATCH] ALSA: usb-audio: Correct wrongly matching entries with audio class
by Takashi Iwai 23 Aug '20

23 Aug '20

The commit 51ab5d77dcb8 ("ALSA: usb-audio: Properly match with audio interface class") converted the quirk entries that have both vid/pid pair and bInterface fields to match with all those with a new macro USB_AUDIO_CLASS(). However, it turned out that those are false conversions; all those (but the unknown KeithMcMillen device) are actually with vendor-specific interface class, hence the conversions broke the matching. This patch corrects those entries to the right one, USB_DEVICE_VENDOR_SPEC() (and USB_DEVICE() for KeithMcMillen to be sure), and drop the unused USB_AUDIO_CLASS macro again.

[PATCH] topology: hda-dsp: Remove srcintc module from HDA DSP topology
by Mateusz Gorski 23 Aug '20

23 Aug '20

The main goal of this topology is to handle every device with hda-dsp configuration on Skylake SST driver. The module_id value for srcintc module varies by FW branch, which makes it impossible to have one universal topology with srcintc module for all of them. Remove srcintc from this topology to make it truly universal.

[PATCH 2/2] ALSA: firewire-digi00x: exclude Avid Adrenaline from detection
by Takashi Sakamoto 23 Aug '20

23 Aug '20

Avid Adrenaline is reported that ALSA firewire-digi00x driver is bound to. However, as long as he investigated, the design of this model is hardly similar to the one of Digi 00x family. It's better to exclude the model from modalias of ALSA firewire-digi00x driver. This commit changes device entries so that the model is excluded. $ python3 crpp < ~/git/am-config-rom/misc/avid-adrenaline.img ROM header and bus information block ----------------------------------------------------------------- 400 04203a9c bus_info_length 4, crc_length 32, crc 15004 404 31333934 bus_name "1394" 408 e064a002 irmc 1, cmc 1, isc 1, bmc 0, cyc_clk_acc 100, max_rec 10 (2048) 40c 00a07e01 company_id 00a07e | 410 00085257 device_id 0100085257 | EUI-64 00a07e0100085257 root directory ----------------------------------------------------------------- 414 0005d08c directory_length 5, crc 53388 418 0300a07e vendor 41c 8100000c --> descriptor leaf at 44c 420 0c008380 node capabilities 424 8d000002 --> eui-64 leaf at 42c 428 d1000004 --> unit directory at 438 eui-64 leaf at 42c ----------------------------------------------------------------- 42c 0002410f leaf_length 2, crc 16655 430 00a07e01 company_id 00a07e | 434 00085257 device_id 0100085257 | EUI-64 00a07e0100085257 unit directory at 438 ----------------------------------------------------------------- 438 0004d6c9 directory_length 4, crc 54985 43c 1200a02d specifier id: 1394 TA 440 13014001 version: Vender Unique and AV/C 444 17000001 model 448 81000009 --> descriptor leaf at 46c descriptor leaf at 44c ----------------------------------------------------------------- 44c 00077205 leaf_length 7, crc 29189 450 00000000 textual descriptor 454 00000000 minimal ASCII 458 41766964 "Avid" 45c 20546563 " Tec" 460 686e6f6c "hnol" 464 6f677900 "ogy" 468 00000000 descriptor leaf at 46c ----------------------------------------------------------------- 46c 000599a5 leaf_length 5, crc 39333 470 00000000 textual descriptor 474 00000000 minimal ASCII 478 41647265 "Adre" 47c 6e616c69 "nali" 480 6e650000 "ne" Reported-by: Simon Wood <simon(a)mungewell.org> Fixes: 9edf723fd858 ("ALSA: firewire-digi00x: add skeleton for Digi 002/003 family") Cc: <stable(a)vger.kernel.org> # 4.4+ Signed-off-by: Takashi Sakamoto <o-takashi(a)sakamocchi.jp> --- sound/firewire/digi00x/digi00x.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/sound/firewire/digi00x/digi00x.c b/sound/firewire/digi00x/digi00x.c index c84b913a9fe0..ab8408966ec3 100644 --- a/sound/firewire/digi00x/digi00x.c +++ b/sound/firewire/digi00x/digi00x.c @@ -14,6 +14,7 @@ MODULE_LICENSE("GPL v2"); #define VENDOR_DIGIDESIGN 0x00a07e #define MODEL_CONSOLE 0x000001 #define MODEL_RACK 0x000002 +#define SPEC_VERSION 0x000001 static int name_card(struct snd_dg00x *dg00x) { @@ -175,14 +176,18 @@ static const struct ieee1394_device_id snd_dg00x_id_table[] = { /* Both of 002/003 use the same ID. */ { .match_flags = IEEE1394_MATCH_VENDOR_ID | + IEEE1394_MATCH_VERSION | IEEE1394_MATCH_MODEL_ID, .vendor_id = VENDOR_DIGIDESIGN, + .version = SPEC_VERSION, .model_id = MODEL_CONSOLE, }, { .match_flags = IEEE1394_MATCH_VENDOR_ID | + IEEE1394_MATCH_VERSION | IEEE1394_MATCH_MODEL_ID, .vendor_id = VENDOR_DIGIDESIGN, + .version = SPEC_VERSION, .model_id = MODEL_RACK, }, {} -- 2.25.1

[PATCH 1/2] ALSA; firewire-tascam: exclude Tascam FE-8 from detection
by Takashi Sakamoto 23 Aug '20

23 Aug '20

Tascam FE-8 is known to support communication by asynchronous transaction only. The support can be implemented in userspace application and snd-firewire-ctl-services project has the support. However, ALSA firewire-tascam driver is bound to the model. This commit changes device entries so that the model is excluded. In a commit 53b3ffee7885 ("ALSA: firewire-tascam: change device probing processing"), I addressed to the concern that version field in configuration differs depending on installed firmware. However, as long as I checked, the version number is fixed. It's safe to return version number back to modalias.

alsa-project/alsa-lib issue #80 was opened from MusicMaker: A device is sending always 3 bytes for note off/on event. The host application uses a virtual port to receive the data The ALSA RAW MIDI API seems to remove the status byte if the channel of the status byte is the same. Once the channel changes, the RAW MIDI API provide the status byte to the higher level layer. Is this the bahaviour of the RAW MIDI API ? if yes then raw isn't actually raw. Can this be disabled ? Could not find a parameter at port open to do this. (not using the sequencer) Issue URL : https://github.com/alsa-project/alsa-lib/issues/80 Repository URL: https://github.com/alsa-project/alsa-lib

[PATCH 1/2] ucm: Add JackSwitch definition
by Curtis Malainey 22 Aug '20

22 Aug '20

Some codecs can differentiate headsets based on the number of rings. Should we choose to differentiate the config we will need to be able to select based on the jack event code.

aserver + shm plug-in information?
by Stuart Longland 22 Aug '20

22 Aug '20

[Hi all, I sent this to the alsa-user list about 2 months ago, and haven't seen any replies. Hoping someone here might know? Thanks in advance.] Hi all, I'm looking at ways to try and share a sound card over a network in a lossless and low-latency manner. The application here will be to be able to use the sound card on a Raspberry Pi to interface to an amateur radio transceiver, and use that interface to send things like slow-scan television from a more powerful workstation. For this to work, it is utterly *essential* that no audio compression is used. So PulseAudio, JACK, etc… unless I'm very much mistaken, are not options as they use lossy audio CODECs for compression. Audio itself might only be 8kHz at 16-bit linear PCM, mono… so not terribly high bit-rate, and even latency is negotiable, but lossy compression is likely to mess things up. PulseAudio I'd imagine is also asking for trouble where digital modes are concerned, as it'll be trying to re-sample everything to keep a consistent sample rate. I want as little extra DSP on streams as possible. I'd prefer to let PulseAudio just handle "audio" only. I'm considering writing an ALSA PCM plug-in to accomplish this, that would expose a "virtual" sound card on my workstation, and allow me to stream it (by custom protocol, RTP, whatever) to another machine. In researching this, I've stumbled on the `shm` plug-in. https://www.alsa-project.org/alsa-doc/alsa-lib/pcm_plugins.html#pcm_plugins… It apparently talks to something called `aserver`. `man aserver` gives me nothing. Google search just takes me to its source code. There seems to be scant information about what this does, how to configure it, etc. Alternatively, it'd be nice to know how `aserver` and the `shm` plug-in communicate, maybe I can write my own client daemon that acts like `aserver` and looks after streaming to the desired end-point. Alternatively, if people feel I'm barking up the wrong tree, I'm willing to consider alternatives. Regards, -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere.

[PATCH 0/2] Add period size constraint for Atom Chromebook
by Brent Lu 21 Aug '20

21 Aug '20

Two different constraints are implemented: one is in platform's CPU DAI to enforce period sizes which are already used in Android BSP. The other is in Atom Chromebook's machine driver to use 240 as period size.
