[PATCH] kselftest/alsa - mixer-test: Don't fail tests if we can't restore default
by Mark Brown 08 Mar '23

08 Mar '23

If a control has an invalid default value then we might fail to set it when restoring the default value after our write tests, for example due to correctly implemented range checks in put() operations. Currently this causes us to report the tests we were running as failed even when the operation we were trying to test is successful, making it look like there are problems where none really exist. Stop doing this, only reporting any issues during the actual test. We already have validation for the initial readback being in spec and for writing the default value back so failed tests will be reported for these controls, and we log an error on the operation that failed when we write so there will be a diagnostic warning the user that there is a problem.

[PATCH 0/130+] ALSA: emu10k1 & more
by Oswald Buddenhagen 08 Mar '23

08 Mar '23

moin, i got myself an old e-mu 0404 card, because i found the analog hardware well hackable for dc operation. then i found the driver to be lacking, and got hacking that, too. hence this blast from the past. this is a huge branch with many internal dependencies, so i'm assuming i'm not supposed to post a patch series. instead it's on https://github.com/ossilator/linux/tree/ossis-alsa - let me know if another review platform is preferable. apart from the actual driver work, this contains some alsa patches unrelated to emu10k1, some patches which really shouldn't be merged via the alsa route (if at all), and some patches which are just collections of questions (to which i hope to receive answers on github). this is of course meant to be cleaned up in due time. feel free to cherry-pick the patches you deem ready; i'll happily rebase the branch. some of these patches are not (fully) tested due to lack of hardware. in particular, someone should check that SB Live! and Audigy cards still work. then there is a whole bunch of e-mu card specific functionality which targets the "bigger members of the family". all patches that need testing are clearly marked as such. if someone wants to provide me with hardware (temporarily or permanently), go ahead (i'm in berlin, germany). on CC is everyone who is recorded to have hacked the emu1010 part of the driver or tested something. i fully expect half the addresses to bounce, and the remainder to wonder what i'm smoking. ;-) when you reply, please do so only to the list and me. regards

[PATCH] ASoC: SOF: sof-audio: add support for setting up topology loopback routes
by Peter Ujfalusi 07 Mar '23

07 Mar '23

From: Chao Song <chao.song(a)linux.intel.com> During route setup, playback stream routes are setup by going through sink path, capture stream routes are set up by going through source path. This is not sufficient to handle loopback cases between pipelines configured with different directions, e.g. a sidetone or an amplifier feedback connected to a speaker protection module. So, add the logic to handle such routes between widgets that aren't in the list of DAPM widgets associated with the same PCM.
