pcm: dshare - fix shared memory pointer check
by GitHub pull_request - opened 21 Mar '21

21 Mar '21

alsa-project/alsa-lib pull request #128 was opened from VanithaChannaiah: Currently shared memory pointer is initialized to 0 and set to -1 in some, but not in all error paths. In cleanup path of open the shm pointer is only compared to be non-NULL before dereferencing it which leads to SEGFAULT in case it was set to -1. This patch initializes pointer to -1 to have a unique identification for invalid pointer and also checks for pointer being not -1 on access in cleanup path.

Pioneer DJ DDJ-SR2 sound degradation
by Geraldo 21 Mar '21

21 Mar '21

Hi everyone, I'm running stable kernel 5.11.6 together with my Pioneer DJ DDJ-SR2 and JACK. Mixxx is running on top of JACK. After I start JACK I have about 40 minutes of good sound quality from the inputs. After this period the sound will begin to degrade slowly until it is almost pure distortion. The issue is gone if I restart the JACK server, no need to reboot the hardware. The description I gave above sounds a lot like soundcard clock drift (which happens to those using more than one soundcard. You know) which motivates me to believe we missed a bug somewhere around the recent changes introduced in implicit feedback sync for Pioneer devices Dyndbg shows nothing useful I guess. No xruns reported. I've recorded a 1KHz tone and after 50+ minutes the sound degradation kicks in. Only problem is even after cutting and encoding to mp3 128kbps it's still a 10 megabytes file. I suppose I could post it to Soundcloud or Mixcloud if anyone is interested. Is anyone else experiencing these symptoms with Pioneer hardware? Note that the sound degradation kicks in after about an hour, more or less, and it's for the inputs only. Outputs continue to operate fine without the need to restart the JACK server every hour. Thanks everybody, Geraldo

[PATCH v2 1/2] ALSA: hda/realtek: fix a determine_headset_type issue for a Dell AIO
by Hui Wang 20 Mar '21

20 Mar '21

We found a recording issue on a Dell AIO, users plug a headset-mic and select headset-mic from UI, but can't record any sound from headset-mic. The root cause is the determine_headset_type() returns a wrong type, e.g. users plug a ctia type headset, but that function returns omtp type. On this machine, the internal mic is not connected to the codec, the "Input Source" is headset mic by default. And when users plug a headset, the determine_headset_type() will be called immediately, the codec on this AIO is alc274, the delay time for this codec in the determine_headset_type() is only 80ms, the delay is too short to correctly determine the headset type, the fail rate is nearly 99% when users plug the headset with the normal speed. Other codecs set several hundred ms delay time, so here I change the delay time to 850ms for alc2x4 series, after this change, the fail rate is zero unless users plug the headset slowly on purpose.

[PATCH 00/14] ASoC: tidyup error message timing
by Kuninori Morimoto 19 Mar '21

19 Mar '21

Hi Mark Indicating error message when failed case is very useful for debuging. In many case, it uses below style. int function(...) { ... return ret; } int caller(...) { ... ret = function(...); if (ret < 0) dev_err(...) ... } This is not so bad, but in this style *each caller* needs to indicate duplicate same error message, and some caller is forgetting to do it. And caller can't indicate detail function() error information. I know many people have many opinion, but if function() indicates error message, we can get same and detail information without forgot, and it is better.

[PATCH v2 0/3] Fix SND_HDA_PREALLOC issue
by Amadeusz Sławiński 19 Mar '21

19 Mar '21

For context it started with user reporting failures when running arecord without any error or warning in dmesg (after fixing some configuration problems thet they had). https://bugzilla.kernel.org/show_bug.cgi?id=201251#c279 After spending time investigating the issue it was narrowed to quite big setting of CONFIG_SND_HDA_PREALLOC_SIZE (4096). When looking at code https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/sou… there is a limit of memory per card: max_alloc_per_card = 32UL * 1024UL * 1024UL When SND_HDA_PREALLOC_SIZE is set to 4096 it only has memory to alloc for 8 frontends, while Skylake HDA card has 10 of them (6 playback and 4 capture), so preallocated memory is exhausted while probing. In consequence 2 of FEs end without allocated memory. It can be workarounded on user side with setting SND_HDA_PREALLOC_SIZE to lower value, other is changing memory limit per card. However in order to not waste user memory, change maximum allocation size on HDA controller to 4MB and force automatical memory allocation insted of preallocated one. First patch adds prints, so similar issues can be easily identified in the future. Second changes maximum size of hda buffer to reasonable value of 4MB. And last one reverts patch which allowed setting prealloc size on X86 platforms.
