[BUG][TGL] Mic is not visible on Surface Pro 8

Open Headcrabed opened this issue 5 months ago • 8 comments

Describe the bug I'm using option snd-intel-dspcfg dsp_driver=3 to enable SOF on Surface Pro 8(1135G7). But after it's enabled, the mic cannot be seen in my KDE sound device list.

To Reproduce Use option snd-intel-dspcfg dsp_driver=3 to force enable SOF, and reboot.

Impact Mic is completely unuseable.

Environment

  1. Branch name and commit hash of the 2 repositories: sof (firmware/topology) and linux (kernel driver).
    • Kernel: Fedora 42 6.15.9
    • SOF: Fedora 42 2025.05-1
  2. Name of the topology file
    • Topology: sof-hda-generic.tplg
  3. Name of the platform(s) on which the bug is observed.
    • Platform: Surface Pro 8

@Headcrabed, did the mic worked when you used the default (legacy) audio stack? Iow, when you did not had option snd-intel-dspcfg dsp_driver=3 specified?

I see that this laptop does not have DMIC, so it should default to legacy HDA stack.

Can you also provide the output of alsa-info.sh --no-upload ?

@ujfalusi Thanks for reply. It partially works if using legacy stack, but there would be extremely high noise for the mic, so still not useable.

I’ll provide script output later when I’m free.

Headcrabed avatar Aug 12 '25 13:08 Headcrabed

@ujfalusi Here they are: alsa-info_dspdriver3.txt alsa-info_nodspdriver.txt

Headcrabed avatar Aug 12 '25 16:08 Headcrabed

@Headcrabed, both alsa-info looks OK, the card is there, controls are as they should be. alsa-ucm-conf is new as well. On a similar HDA only laptop with forced SOF: kernel: 6.15.8-artix1-1, alsa-ucm-conf-1.2.14-2, pipewire-1:1.4.7-1.1, wireplumber-0.5.10-1 : Image

There is however something odd about how PW works: if I use Plasma X11 session, both PW and WP goes to , but if I use Plasma Wayland session, then everything is working fine.

Can you provide the output of alsaucm dump text when using SOF stack?

If the mic is not working correctly with the legacy stack then it is not going to work with SOF either, it is a codec configuration issue and this laptop might need some HDA quirk to be applied to behave correctly.

I cannot find any hint that people ever tested the mic on SP8 (https://github.com/linux-surface/linux-surface/wiki/Supported-Devices-and-Features#feature-matrix), it might never worked under Linux?

Do both internal and headset mic have the same quality issue (with the legacy stack)? Can you provide recording?

Also I can't test in-device headphone jack, as I don't have a 3.5mm mic. For internal mic, I'll test it later.

@ujfalusi Audio sample here: https://1drv.ms/u/c/5a75826b06294adb/EbuYXYY60EZHp1CWZ7gR6lAB_IRPthMIJb1TbQMljUEzjQ?e=ZbGeY8

Can you try to lower the boost on the internal mic: amixer -c0 sset 'Internal Mic Boost' 0

In case of SOF it is ucm that is confused since this mixer representation is something that we have never seen.

Does this device have 3.5mm Jack at all?

Can you paste the output of amixer -c0 contents and amixer -c0 scontents for my collection in hopes that I can try to fix UCM, but again, on this device SOF is not really needed for audio.

ujfalusi avatar Aug 14 '25 11:08 ujfalusi

@ujfalusi amixer -c0 sset 'Internal Mic Boost' 0 helps! Seems the default value is set to 3. And yes it has a 3.5mm jack.
