With SOF enabled in sof-hda-generic.tplg device (no DMIC) the control 'Capture Source' is not controlled by UCM
by GitHub issues - opened 05 Dec '24

05 Dec '24

alsa-project/alsa-ucm-conf issue #484 was opened from singalsu: The configuration is not usual. If there is no DMIC in the system usually the legacy mode is selected (as with `options snd_intel_dspcfg dsp_driver=1`). In such PCs SOF can be enabled with `options snd_intel_dspcfg dsp_driver=3`. When a headset is plugged/unplugged the playback correctly switches between speaker and headphone/headset earbuds. But the microphone capture remains muted. I noticed with legacy mode where internal microphones work that control name='Capture Source' changes to 1 when headset is removed: ``` singalsu@asteri:~$ amixer -c0 cget name='Capture Source' numid=6,iface=MIXER,name='Capture Source' ; type=ENUMERATED,access=rw------,values=1,items=2 ; Item #0 'Headset Mic' ; Item #1 'Internal Mic' : values=1 singalsu@asteri:~$ amixer -c0 cget name='Capture Source' numid=6,iface=MIXER,name='Capture Source' ; type=ENUMERATED,access=rw------,values=1,items=2 ; Item #0 'Headset Mic' ; Item #1 'Internal Mic' : values=0 ``` This is not happening when SOF is enabled. But I could make internal microphones capture work with `amixer -c0 cset name='Capture Source' 1`. Is there a way to fix this in ucm2? I'm not absolutely sure about this issue in Fedora 41 but this happens with my modified ucm2 development code with git master branch.

aplay doesn't play audio sometimes "unable to open slave"

alsa-project/alsa-lib issue #426 was opened from haoyi-codes: I have initially thought it was a bug that was related to chromium as stated in #425. However, now I realize it has to be something else that is wrong. `aplay -D default /dev/zero` ``` ALSA lib /var/tmp/portage/media-libs/alsa-lib-1.2.13/work/alsa-lib-1.2.13/src/pcm/pcm_dmix.c:1000:(snd_pcm_dmix_open) unable to open slave aplay: main:850: audio open error: No such file or directory ``` `aplay -D plughw:0 /dev/zero` ``` aplay: main:850: audio open error: No such file or directory ``` `aplay -l` ``` **** List of PLAYBACK Hardware Devices **** card 0: NVidia [HDA NVidia], device 3: Generic Digital [Generic Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: HDMI [HDA ATI HDMI], device 3: Generic Digital [Generic Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: Audio [SA9123 USB Audio], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 ``` `cat /proc/asound/cards` ``` 0 [NVidia ]: HDA-Intel - HDA NVidia HDA NVidia at 0x81080000 irq 17 1 [HDMI ]: HDA-Intel - HDA ATI HDMI HDA ATI HDMI at 0x81220000 irq 165 2 [Audio ]: USB-Audio - SA9123 USB Audio SYC SA9123 USB Audio at usb-0000:00:14.0-3.2, full speed 3 [Edition ]: USB-Audio - Logi 4K Stream Edition Logi 4K Stream Edition at usb-0000:00:14.0-3.3, super speed ``` `ls -la /dev/snd/*` ``` crw-rw----+ 1 root audio 116, 0 Dec 4 23:18 /dev/snd/controlC0 crw-rw----+ 1 root audio 116, 32 Dec 4 23:18 /dev/snd/controlC1 crw-rw----+ 1 root audio 116, 64 Dec 4 23:18 /dev/snd/controlC2 crw-rw----+ 1 root audio 116, 96 Dec 4 23:18 /dev/snd/controlC3 crw-rw----+ 1 root audio 116, 19 Dec 4 23:18 /dev/snd/pcmC0D3p crw-rw----+ 1 root audio 116, 51 Dec 4 23:18 /dev/snd/pcmC1D3p crw-rw----+ 1 root audio 116, 80 Dec 4 23:18 /dev/snd/pcmC2D0p crw-rw----+ 1 root audio 116, 120 Dec 4 23:18 /dev/snd/pcmC3D0c crw-rw----+ 1 root audio 116, 1 Dec 4 23:18 /dev/snd/seq crw-rw----+ 1 root audio 116, 33 Dec 4 23:18 /dev/snd/timer /dev/snd/by-id: total 0 drwxr-xr-x 2 root root 80 Dec 4 23:18 . drwxr-xr-x 4 root root 280 Dec 4 23:17 .. lrwxrwxrwx 1 root root 12 Dec 4 23:18 usb-046d_Logi_4K_Stream_Edition_51C07EAF-03 -> ../controlC3 lrwxrwxrwx 1 root root 12 Dec 4 23:18 usb-SYC_SA9123_USB_Audio-01 -> ../controlC2 /dev/snd/by-path: total 0 drwxr-xr-x 2 root root 160 Dec 4 23:18 . drwxr-xr-x 4 root root 280 Dec 4 23:17 .. lrwxrwxrwx 1 root root 12 Dec 4 23:18 pci-0000:00:14.0-usb-0:3.2:1.1 -> ../controlC2 lrwxrwxrwx 1 root root 12 Dec 4 23:18 pci-0000:00:14.0-usb-0:3.3:1.3 -> ../controlC3 lrwxrwxrwx 1 root root 12 Dec 4 23:18 pci-0000:00:14.0-usbv2-0:3.2:1.1 -> ../controlC2 lrwxrwxrwx 1 root root 12 Dec 4 23:18 pci-0000:00:14.0-usbv3-0:3.3:1.3 -> ../controlC3 lrwxrwxrwx 1 root root 12 Dec 4 23:18 pci-0000:01:00.1 -> ../controlC0 lrwxrwxrwx 1 root root 12 Dec 4 23:18 pci-0000:05:00.1 -> ../controlC1 ``` For reference I am still able to play audio on my system as pulseaudio is running but for applications that use alsa directly it does not work. ``` Server String: /run/user/1011/pulse/native Library Protocol Version: 35 Server Protocol Version: 35 Is Local: yes Client Index: 59 Tile Size: 65472 User Name: user Host Name: system Server Name: PulseAudio (on PipeWire 1.2.7) Server Version: 15.0.0 Default Sample Specification: float32le 2ch 48000Hz Default Channel Map: front-left,front-right Default Sink: alsa_output.usb-SYC_SA9123_USB_Audio-01.iec958-stereo Default Source: alsa_output.usb-SYC_SA9123_USB_Audio-01.iec958-stereo.monitor Cookie: XXXX:XXXX ``` Issue URL : https://github.com/alsa-project/alsa-lib/issues/426 Repository URL: https://github.com/alsa-project/alsa-lib

pulseaudio bails out on 1.2.13 (SIGSEGV), with MOTU Ultralite mk5
by GitHub issues - opened 04 Dec '24

04 Dec '24

alsa-project/alsa-ucm-conf issue #483 was opened from karolyi: Hey, I have this sound card and with the latest update (1.2.13), pulseaudio started to SIGSEGV and I have no sound. Upon going to the pulseaudio IRC channel and talking to the devs, we've managed to point out that it's the UCM configuration that makes pulseaudio crash. Reverting to 1.2.12 made the crash cease. It seems that the newly added configuration for the Ultralite makes pulseaudio crash. According to the below gdb traces, it seems the configuration drives pulseaudio into an infinite loop. Beginning of the trace: ``` Debuginfod has been enabled. To make this setting permanent, add 'set debuginfod enabled on' to .gdbinit.

alsa-project/alsa-ucm-conf issue #482 was edited from singalsu: It seems updates have dropped .conf from looked up SOF blobs customization files. Is the change intentional? Then the example in ucm2/blobs/sof/product_configs/AAEON/UPX-TGL01.conf should be renamed to be without .conf to work and to be applied correctly.

UCM2: Intel: sof-hda-dsp: Enable Dmic0 DRC and TDFB pre-processing
by GitHub pull_request - opened 03 Dec '24

03 Dec '24

alsa-project/alsa-ucm-conf pull request #481 was opened from singalsu: This patch adds enable of the microphone capture pre-processing features as BootSequence inital values if the controls for them are available. If the user later switches these off, they will remain off. The DRC is dynamic range control that boosts the capture level, and the TDFB (time-domain fixed beamformer) improves capture signa-to-noise ratio for set beam angle direction. The used 0 degrees angle is defined as angle towards notebook computer user.

AFAIK, in the driver side, there is not much special; it assumes that DSD samples are passed over the standard PCM stream, and the driver uses special formats SNDRV_PCM_FORMAT_DSD_U8, *_U16 and *_U32 (with _LE and _BE suffix) for 8, 16 and 32bit, instead of the standard SNDRV_PCM_FORMAT_U8, *_S16, etc. For those formats, the silence data is assumed to be 0x69, 0x6969, etc. Takashi
