[PATCH] ASoC: Intel: Do not load legacy SST driver on BYT when SND_SOC_SOF_BAYTRAIL is enabled
by Hans de Goede 12 Oct '20

12 Oct '20

The legacy 80860F28 / sst_acpi_baytrail_desc match in sst_acpi_match is already conditional on the the newer SND_SST_IPC_ACPI driver not being enabled. But now that we have an even newer driver in the form of SOF support for BYT devices, we also need to take this into account, so we also must not include the sst_acpi_baytrail_desc match when SND_SOC_SOF_BAYTRAIL is enabled. This fixes snd-soc-sst-acpi binding to the 80860F28 platform device, blocking snd-sof-acpi from binding, which breaks audio support.

Buggy hardware mixing
by Kevin Maciel 11 Oct '20

11 Oct '20

Hi all, I was referred here from the #alsa irc channel on freenode. I've been having issues with hardware mixing in ALSA since I started using Linux at least 10 years ago. Sometimes when I am trying to play multiple audio sources at once, one source will stop producing sound or all sound will all of a sudden turn into a mash of loud, jumbled noise. This has occurred across every combination of hardware and distribution of Linux I have used for my personal computers. I was trying to set up a custom dmix configuration to work around the problem, but I could not get multiple audio sources to play with my custom dmix definition. It seems to work if I use dmix:CARD=xxx, but I would like to set my own period_size and other such settings. I was told it is a better idea to try to figure out what the problem is with hardware mixing than to try to work around it with dmix. So here we are. I always thought this was a known problem and that hardware mixing by default was considered "new" or experimental. Thanks

I managed to get it to work with the following patch: diff --git a/src/pcm/pcm_plugin.c b/src/pcm/pcm_plugin.c index ea60eb98..89e819d6 100644 --- a/src/pcm/pcm_plugin.c +++ b/src/pcm/pcm_plugin.c @@ -551,6 +551,8 @@ static int snd_pcm_plugin_status(snd_pcm_t *pcm, snd_pcm_status_t * status) return err; status->appl_ptr = *pcm->appl.ptr; status->hw_ptr = *pcm->hw.ptr; + status->avail = snd_pcm_mmap_capture_avail(pcm); + status->delay = snd_pcm_mmap_capture_delay(pcm); return 0; } My question is if this is the correct solution?

[PATCH 1/1] ALSA: hda: fix jack detection with Realtek codecs when in D3
by Kai Vehmanen 09 Oct '20

09 Oct '20

In case HDA controller is active, but codec is runtime suspended, jack detection is not successful and no interrupt is raised. This has been observed with multiple Realtek codecs and HDA controllers from different vendors. Bug does not occur if both codec and controller are active, or both are in suspend. Bug can be easily hit on desktop systems with no built-in speaker. The problem can be fixed by powering up the codec once after every controller runtime resume. Even if codec goes back to suspend, the jack detection will now work. Add a flag to 'hda_codec' to describe codecs that require this flow from the controller driver. Mark all Realtek codecs with this flag.

[PATCH] ALSA: hda/i915 - fix list corruption with concurrent probes
by Kai Vehmanen 09 Oct '20

09 Oct '20

From: Takashi Iwai <tiwai(a)suse.de> Current hdac_i915 uses a static completion instance to wait for i915 driver to complete the component bind. This design is not safe if multiple HDA controllers are active and communicating with different i915 instances, and can lead to list corruption and failed audio driver probe. Fix the design by moving completion mechanism to common acomp code and remove the related code from hdac_i915.
