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

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... for more information.

Dear Yu-Hsuan,
Yes, using card index and device index works. Here is the output:

As I mentioned earlier I am interested in card 1, the seeed8micvoicec entry. Here it is the conformance test output:
20 passed, 0 failed Device Information Name: hw:CARD=1,0 Stream: PLAYBACK Format: ['S32_LE'] Channels: [8] Rate: [8000, 11025, 16000, 22050, 44100, 48000] Period_size range: [8, 8192] Buffer_size range: [16, 16384] Test Params Set channels 8: pass Set format S32_LE: pass Set rate 8000: pass Set rate 11025: pass Set rate 16000: pass Set rate 22050: pass Set rate 44100: pass Set rate 48000: pass Test Rates Set rate 8000: pass Set rate 11025: pass Set rate 16000: pass Set rate 22050: pass Set rate 44100: pass Set rate 48000: pass Test All Pairs Set channels 8, format S32_LE, rate 8000: pass Set channels 8, format S32_LE, rate 11025: pass Set channels 8, format S32_LE, rate 16000: pass Set channels 8, format S32_LE, rate 22050: pass Set channels 8, format S32_LE, rate 44100: pass Set channels 8, format S32_LE, rate 48000: pass
There is probably a bug somewhere on not being able to use the card name?

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.

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/+/1.... Waiting for the review and merge. Thanks a lot for your catch!

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:
