Add persistent ID's for soundcards and midi devices (like coreaudio)
by GitHub issues - opened 18 Aug '24

18 Aug '24

alsa-project/alsa-lib issue #407 was opened from sjomae: "This is something where macOS' Coreaudio/MIDI shines. Unlike macOS Linux/ALSA has no persistent unique IDs for soundcards or MIDI devices. ALSA supports hotplug, and first come first server sequential numeric IDs. The best you^Wpipewire can do is keep track of cards by name. So this is not something pipewire can reliably address, until ALSA get support to identify cards by vendor and serial-number, and provide a UUID." https://lists.linuxaudio.org/hyperkitty/list/linux-audio-dev@lists.linuxaud… Issue URL : https://github.com/alsa-project/alsa-lib/issues/407 Repository URL: https://github.com/alsa-project/alsa-lib

alsa-project/alsa-ucm-conf issue #437 was opened from Gess79: I hope I'm correct to post this here. Still new to things Linux. **Situation** OS: Kubuntu 24.04 Mainboard = ASUS ROG Maximus Z790 Hero USB Audio = 0b05:1a53 ASUSTek Computer, Inc. USB Audio Speakers = Logitech Z906 Surround Kernel = 6.8.0-40-generic Alsa version = 1.2.9 **Issue** The speakers seem to be assigned incorrectly and the subwoofer isn't working. I'm testing the speakers through pulseaudio as follows: ![image](https://github.com/user-attachments/assets/8bf65600-63ad-46cc-af68-d51ab6d4a7e6) I'm listing the results below in three categories: - The icon clicked within pulseaudio - The soundfile played - The speaker the sound is actually output to _Icon clicked - Soundfile played - Physical speaker output_ Front Left - Front Left - Front Left Front Center - Front Center - Rear Left Front Right - Front Right - Front Right Rear Left - Rear Left - Front Center Subwoofer - Rear Center - Rear Right Rear Right - (nothing) - (nothing) I've had a lengthy discussion on Reddit but I couldn't find a fix for it so far: https://www.reddit.com/r/linux4noobs/comments/1980uv1/comment/kieqsor/ I'm happy to provide all information necessary to pinpoint the issue and fix it.

Use PyBytes and not Unicode strings for IEC958 values
by GitHub pull_request - edited 16 Aug '24

16 Aug '24

alsa-project/alsa-python pull request #14 was edited from tormodvolden: Suggested fix for #13. - the first commit is not strictly related but also needed to avoid hctltest1.py crashing with my audio devices, where some have info.count = 0. Let me know if more information is needed. I don't know if this is expected or if a warning should be issued. - I went for PyBytes instead of PyByteArray - for setting values, if the provided PyBytes value is shorter than the value, it will be zero-padded. - if it is too long, it will be silently truncated - following the existing code style, no empty lines were inserted, but this could help readability - the third commit is not for fixing the crash, but for fixing set_tuple() to actually do anything for IEC958 - I haven't changed the reference counting, which seems wrong to me in the original code as well. This would be a different issue.

[PATCH] ASoC: dt-bindings: qcom,lpass-wsa-macro: correct clocks on SM8250
by srinivas.kandagatla＠linaro.org 16 Aug '24

16 Aug '24

From: Srinivas Kandagatla <srinivas.kandagatla(a)linaro.org> we seems to have ended up with duplicate clocks for frame-sync on sm8250, it has both va and fsgen which are exactly same things. Remove the redundant va clock and make it align with other SoCs. Codec driver does not even handle va clock, so remove this from the bindings and examples to avoid any confusion.

[PATCH] ASoC: SOF: amd: Fix for acp init sequence
by Vijendar Mukunda 16 Aug '24

16 Aug '24

When ACP is not powered on by default, acp power on sequence explicitly invoked by programming pgfsm control mask. The existing implementation checks the same PGFSM status mask and programs the same PGFSM control mask in all ACP variants which breaks acp power on sequence for ACP6.0 and ACP6.3 variants. So to fix this issue, update ACP pgfsm control mask and status mask based on acp descriptor rev field, which will vary based on acp variant.
