[PATCH alsa-ucm-conf] sof-soundwire: Split cs42l43 dmic initialisation
by Charles Keepax 10 Mar '25

10 Mar '25

Split the initialisation of cs42l43 into a headset part and a dmic part. This will prevent the dmic mute controls getting attached to the mute LED when the codec dmics are not being used.

Channel count in Focusrite Scarlett Gen 4 (1235:8218) SplitPCM configuration
by GitHub issues - edited 09 Mar '25

09 Mar '25

alsa-project/alsa-ucm-conf issue #515 was edited from pv: The configuration https://github.com/alsa-project/alsa-ucm-conf/blob/master/ucm2/USB-Audio/Fo… specifies `HWChannels 2` for the Mic1 and Mic2 devices. This gets translated to `CaptureChannels 2` for `alsaucm open '<<<SplitPCM=1>>>hw:2'`. However, we've got a report https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/4597#note_2815906 that looks like snd_pcm_hw_params_set_channels(pcm_handle, hwparams, 2) for the CapturePCM "_ucm0001.hw:Gen,0" fails with error. The PCM can be opened with 4 channels, though. Without `SplitPCM=1`, it also probably works but I'm not sure what channel count the `dshare` plugin is using. The issue also affects the `Direct` profile, which also specifies `CaptureChannels 2`. Is the `HWChannels 2` for Mic1/2 input direction right? Shall `CaptureChannels 2` in UCM device be interpreted as that the device can be opened with exactly 2 channels, or that it can be opened with some number of channels >= 2? <details> ``` $ alsaucm open '<<<SplitPCM=1>>>hw:2' dump text Verb.HiFi { Comment Default Device.Line1 { Comment "Headphones / Line 1-2" Values { CaptureCTL "_ucm0001.hw:Gen" PlaybackCTL "_ucm0001.hw:Gen" PlaybackPCM "_ucm0001.hw:Gen" PlaybackPriority 200 } } Device.Mic1 { Comment "Input 1 Mic/Inst/Line" Values { CaptureCTL "_ucm0001.hw:Gen" CaptureChannel0 0 CaptureChannelPos0 MONO CaptureChannels 2 CapturePCM "_ucm0001.hw:Gen,0" CapturePriority 200 PlaybackCTL "_ucm0001.hw:Gen" } } Device.Mic2 { Comment "Input 2 Mic/Inst/Line" Values { CaptureCTL "_ucm0001.hw:Gen" CaptureChannel0 1 CaptureChannelPos0 MONO CaptureChannels 2 CapturePCM "_ucm0001.hw:Gen,0" CapturePriority 100 PlaybackCTL "_ucm0001.hw:Gen" } } } Verb.Direct { Comment "Direct Scarlett Solo 4th Gen" Device.Direct { Comment "Direct Scarlett Solo 4th Gen" Values { CaptureCTL "_ucm0001.hw:Gen" CaptureChannels 2 CapturePCM "_ucm0001.hw:Gen" CapturePriority 1000 PlaybackCTL "_ucm0001.hw:Gen" PlaybackChannels 2 PlaybackPCM "_ucm0001.hw:Gen" PlaybackPriority 1000 } } } ``` </details> Issue URL : https://github.com/alsa-project/alsa-ucm-conf/issues/515 Repository URL: https://github.com/alsa-project/alsa-ucm-conf

PORT: GTK2 to GTK3
by GitHub pull_request - opened 07 Mar '25

07 Mar '25

alsa-project/alsa-tools pull request #27 was opened from genbtc: I've undertaken a task of porting alsa-tools programs from GTK2 to GTK3. These patches start with a base of 5eaadd15bda4cf0424ee2470a6d304a0c2ce10cb (master) Date: Mon Jan 27 (latest pull) Results: Compilation completes successfully, Linked to GTK3, but I do not have the hardware cards to test run them. All work has been done by me, and I request a code review on the GDK 2 Pixmap to GDK 3 Pixbuf + Cairo surfaces. Like it needs new logic and new plan. not simply change statement A to B (whatever I did to get it to compile) I tried to comply with the existing style, and There was also a fair bit of inconsequential whitespace removed like (\n\t\n) or trailing space chars as I discovered them. Looking forward to upstreaming these changes somehow if you would like to work on this. - genBTC @ gentoo Request URL : https://github.com/alsa-project/alsa-tools/pull/27 Patch URL : https://github.com/alsa-project/alsa-tools/pull/27.patch Repository URL: https://github.com/alsa-project/alsa-tools

Multiple CODECs on > the same link is the main use case for set_tdm_slot(). Thanks for the advice.The method you mentioned could work. I will modify my driver.
