[alsa-devel] alsa conformance test fails to run for playback (and works for capture)

[alsa-devel] alsa conformance test fails to run for playback (and works for capture)

[Hin-Tak Leung]

Hi Yu-Hsuan,

I have encountered another problem with the alsa conformance test. It works for capture, but not for playback.

The device is - 

http://wiki.seeedstudio.com/ReSpeaker_6-Mic_Circular_Array_kit_for_Raspberry_Pi/

and running on a pi / raspbian buster.

The actual message is:

Fail - ALSA lib pcm_hw.c:1822:(_snd_pcm_hw_open) Invalid value for card
snd_pcm_open hw:CARD=seeed8micvoi: No such device

I think the truncation is harmless .

The actual device name according to aplay -L is "hw:CARD=seeed8micvoicec,DEV=0" and as I noted earlier, arecord -L shows it as "hw:CARD=seeed8micvoicec,DEV=0" also, and the comformance test running in CAPTURE mode works, just not in PLAYBACK mode.

Is there anything I can do to look further?

Since it says "invalid value", I tried deleting the parameters around line 190 of src/alsa_conformance_helper.c, but perhaps I should do something else?

src/alsa_conformance_helper.c-191-    conformance_timer_start(timer, SND_PCM_OPEN);
src/alsa_conformance_helper.c:192:    rc = snd_pcm_open(handle,
src/alsa_conformance_helper.c-193-                      dev_name,
src/alsa_conformance_helper.c-194-                      stream,
src/alsa_conformance_helper.c-195-                      SND_PCM_NONBLOCK |
src/alsa_conformance_helper.c-196-                      SND_PCM_NO_AUTO_RESAMPLE |
src/alsa_conformance_helper.c-197-                      SND_PCM_NO_AUTO_CHANNELS |
src/alsa_conformance_helper.c-198-                      SND_PCM_NO_AUTO_FORMAT);
src/alsa_conformance_helper.c-199-    conformance_timer_stop(timer, SND_PCM_OPEN);

Hin-Tak

Hi Hin-Tak,

How about using index instead? You should find the card index and device
index by running "aplay -l" command. The pcm format
is hw:{CARD_INDEX},{DEVICE_INDEX}.
See example part in
https://chromium.googlesource.com/chromiumos/platform/audiotest/+/refs/heads/master/alsa_conformance_test.md
for
more information.

Best,
Yu-Hsuan

Dear Yu-Hsuan,

Yes, using card index and device index works. Here is the output:

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: ALSA [bcm2835 ALSA], device 0: bcm2835 ALSA [bcm2835 ALSA]

 Subdevices: 1/1
 Subdevice #0: subdevice #0

As I mentioned earlier I am interested in card 1, the seeed8micvoicec entry. Here it is the conformance test output: 


20 passed, 0 failed

There is probably a bug somewhere on not being able to use the card name?

Hin-Tak

Hi Hin-Tak,
Maybe it is not the correct pcm name.  I guess the correct one is
"hw:seeed8micvoicec,0". Could you try it?
By the way, you can also use aplay -D {device_name} to make sure
whether the name is correct or not.

Best,
Yu-Hsuan

Dear Yu-Hsuan,

No "hw:seeed8micvoicec,0" did not work as input to the conformance test. As input to 'aplay -D', both the ,0 and without it sort of works.
(it waits for input from stdin).

When I actually gave it an channel file to play, both forms ('aplay -D hw:CARD=seeed8micvoicec ...' and 'aplay -D hw:CARD=seeed8micvoicec,0 ...') stopped with:

Playing WAVE 'Untitled recording 2019-10-11 19.15.11.wav' : Signed 16 bit Little Endian, Rate 16000 Hz, Channels 6
aplay: set_params:1339: Sample format non available
Available formats:
- S32_LE

The interesting part of 'aplay -L' is (there is another device):

sysdefault:CARD=seeed8micvoicec
 seeed-8mic-voicecard, 
 Default Audio Device
dmix:CARD=seeed8micvoicec,DEV=0
 seeed-8mic-voicecard, 
 Direct sample mixing device
dsnoop:CARD=seeed8micvoicec,DEV=0
 seeed-8mic-voicecard, 
 Direct sample snooping device
hw:CARD=seeed8micvoicec,DEV=0
 seeed-8mic-voicecard, 
 Direct hardware device without any conversions
plughw:CARD=seeed8micvoicec,DEV=0
 seeed-8mic-voicecard, 
 Hardware device with all software conversions
usbstream:CARD=seeed8micvoicec
 seeed-8mic-voicecard
 USB Stream Output

As I mentioned at the beginning, 'arecord -L' and running the conformance test in CAPTURE mode using 'hw:CARD=seeed8micvoicec' works. It is PLAYBACK which does not.

Regards,
Hin-Tak

[Yu-Hsuan Hsu]

Hi Hin-Tak,

I finally found out the reason! It is because there is a length limit
of PCM name in ALSA conformance test.
I have increased it on
https://chromium-review.googlesource.com/c/chromiumos/platform/audiotest/+/1871792.
Waiting for the review and merge.
Thanks a lot for your catch!

Best,
Yu-Hsuan

Dear Yu-Hsuan,

Yes, I hand-applied the one-line change, and it now works. I do wonder if you should change the args_set_capture_dev_name() also? 
At the moment, MAX_DEVICE_NAME_LENGTH is only used in exactly one place, for the playback device name. Hence the surprise that
capture works but playback does not:

src/alsa_conformance_args.c-119-void args_set_playback_dev_name(struct alsa_conformance_args *args,
src/alsa_conformance_args.c-120- const char *name)
src/alsa_conformance_args.c-121-{
src/alsa_conformance_args.c-122- free(args->playback_dev_name);
src/alsa_conformance_args.c:123: args->playback_dev_name = strndup(name, MAX_DEVICE_NAME_LENGTH);
src/alsa_conformance_args.c-124-}
src/alsa_conformance_args.c-125-
src/alsa_conformance_args.c-126-void args_set_capture_dev_name(struct alsa_conformance_args *args,
src/alsa_conformance_args.c-127- const char *name)
src/alsa_conformance_args.c-128-{
