alsa-project/alsa-ucm-conf pull request #545 was opened from serhii-nakon: Support of - volume control - un/mute control PS: About un/mute control - only from PC to Mic, vise versa does not work - like when you un/mute Mic on PC it works as expected (even LED show actual status) but when you click button on Mic side it does not reflect on PC side.

Dell Precision 3571: DMIC not detected by SOF driver, silent mic under Linux, works in Windows
by Adam Larios 08 Apr '25

08 Apr '25

*System*: Dell Precision 3571 Realtek ALC3204 codec Intel Alder Lake (SOF platform) *Symptoms*: Internal mic is silent or muffled in all Linux applications Works perfectly in Windows SOF driver loads correctly with firmware sof-adl.ri and topology sof-hda-generic.tplg But dmesg shows: sof-audio-pci-intel-tgl 0000:00:1f.3: DMICs detected in NHLT tables: 0 No working audio input nodes exposed in PipeWire *Tested*: - Ubuntu 24.04 with kernel 6.8.0-57-generic - snd-intel-dspcfg.dsp_driver=3 set - PulseAudio and PipeWire backends - alsa-base.conf overrides for model options - hdajackretask pin remapping - SOF firmware and topology confirmed present *Conclusion*: Firmware/ACPI likely missing DMIC NHLT entry; requesting kernel quirk or guidance

Fireworks Alsa Driver Buffer SIze
by jayt0808＠gmail.com 08 Apr '25

08 Apr '25

Hi I'm using an AudioFire 8a that has 16 channels over the firewire bus and the snd-fireworks alsa firewire driver. In Jack, when I set Frames/Period to anything higher than 64, alsa fails with an error saying Mon Apr 7 22:15:35 2025: ERROR: ALSA: cannot set hardware parameters for capture Mon Apr 7 22:15:35 2025: ERROR: ALSA: cannot configure capture channel I noticed that the output of "aplay -D hw:1,0 --dump-hw-params /dev/zero" indicated the following alsa settings: Playing raw data '/dev/zero' : Unsigned 8 bit, Rate 8000 Hz, Mono HW Params of device "hw:1,0": -------------------- ACCESS: MMAP_INTERLEAVED RW_INTERLEAVED FORMAT: S32_LE SUBFORMAT: STD SAMPLE_BITS: 32 FRAME_BITS: [384 512] CHANNELS: [12 16] RATE: [32000 96000] PERIOD_TIME: [250 32000] PERIOD_SIZE: [16 2720] PERIOD_BYTES: [768 131072] PERIODS: [2 341] BUFFER_TIME: (333 170500] BUFFER_SIZE: [32 5456] BUFFER_BYTES: [1536 262144] TICK_TIME: ALL -------------------- aplay: set_params:1371: Sample format non available Available formats: - S32_LE I was concerned that the BUFFER_SIZE was too small to support 16 channels at a 128 Frames/Period size. But when I modded the driver to increase this figure, it did not fix the issue. Anyone have any insight on this issue? Running Ubuntu 24.04 with kernel 6.8.0-57-lowlatency. Everything seems to work fine when I set 64 Frames/Period (except the occasional annoying stuttering that one can expect in that scenario; with a buffer that is too small to support the system load). Thanks Jay

[PATCH v2] ASoC: dwc: always enable/disable i2s irqs
by Brady Norander 08 Apr '25

08 Apr '25

Commit a42e988 ("ASoC: dwc: add DMA handshake control") changed the behavior of the driver to not enable or disable i2s irqs if using DMA. This breaks platforms such as AMD ACP. Audio playback appears to work but no audio can be heard. Revert to the old behavior by always enabling and disabling i2s irqs while keeping DMA handshake control.

pcm: hw: do not reset tstamp_type in SND_PCM_APPEND mode
by GitHub pull_request - opened 06 Apr '25

06 Apr '25

alsa-project/alsa-lib pull request #450 was opened from kgroeneveld: When the first client of plugins such as dshare open the hw device they set a default tstamp_type in snd_pcm_direct_initialize_slave based on tstamp_type from the config file. But when subsequent clients open the same plugin the snd_pcm_hw_open_fd function clobbers this default.
