Overflow in calculating audio timestamp
by Alan Young 06 Feb '23

06 Feb '23

sound/core/pcm_lib.c:update_audio_tstamp() contains the following calculation: audio_nsecs = div_u64(audio_frames * 1000000000LL, runtime->rate); This will result in a 64-bit overflow after 4.4 days at 48000 Hz, or 1.1 days at 192000. Are you interested in a patch to improve this? The same calculation occurs in a couple of other places. Alan.

sample_size field in snd_dec_flac structure
by Carlos Rafael Giani 06 Feb '23

06 Feb '23

In snd_dec_flac (see: https://github.com/torvalds/linux/blob/master/include/uapi/sound/compress_p… ), there is the sample_size field. It seems to me that this is meant to contain the same value as the sample size as the one in the frame header: https://xiph.org/flac/format.html#frame_header Does this mean that if I always send a full FLAC stream into the device, with its complete STREAMINFO header, I can just always set sample_size to 0? The spec does mention that 0 mean "get [the sample size] from STREAMINFO metadata block".

Make ALC4080 front panel audio work on ASUS ROG STRIX X670E-E GAMING WIFI

Hi In order to have working front panel audio for my computer based on a ASUS ROG STRIX X670E-E GAMING WIFI motherboard with ALC4080 audio, I need to apply the following patch. It would be great if it could be applied up-stream so I (and other users with the same hardware) don't have to do this manually in the future.

[PATCH] kselftest/alsa: Run PCM tests for multiple cards in parallel
by Mark Brown 04 Feb '23

04 Feb '23

With each test taking 4 seconds the runtime of pcm-test can add up. Since generally each card in the system is physically independent and will be unaffected by what's going on with other cards we can mitigate this by testing each card in parallel. Make a list of cards as we enumerate the system and then start a thread for each, then join the threads to ensure they have all finished. The threads each run the same tests we currently run for each PCM on the card before exiting. The list of PCMs is kept global since it helps with global operations like working out our planned number of tests and identifying missing PCMs and it seemed neater to check for PCMs on the right card in the card thread than make every PCM loop iterate over cards as well. We don't run per-PCM tests in parallel since in embedded systems it can be the case that resources are shared between the PCMs and operations on one PCM on a card may constrain what can be done on another PCM on the same card leading to potentially unstable results. We use a mutex to ensure that the reporting of results is serialised and we don't have issues with anything like the current test number, we could do this in the kselftest framework but it seems like this might cause problems for other tests that are doing lower level testing and building in constrained environments such as nolibc so this seems more sensible. Note that the ordering of the tests can't be guaranteed as things stand, this does not seem like a major problem since the numbering of tests often changes as test programs are changed so results parsers are expected to rely on the test name rather than the test numbers. We also now prefix the machine generated test name when printing the description of the test since this is logged before streaming starts. On my two card desktop system this reduces the overall runtime by a third.
