soundcard not working. chromebook pixel LS unstable 5.10.0-7

#1 Post by invoker »

On the chromebook pixel LS I own, I installed debian testing without a desktop environment, but grabbed networkmanager and i3 during installation. Network works correctly, the touchpad works adequately, but the sound card does not work properly. I cannot use the speakers or the headphone jack at all.

at one point in the past, my sound worked on debian. I remember seeing a bdwrt5677 device in pavucontrol at that time, but now all I have is the intel HDA sound card and a dummy output.

I installed the firmware-intel-sound package to resolve a missing SST2 firmware problem in dmesg, but doing so introduced more errors. For example, when the SST2 driver is loaded, suspending and shutting down the computer using systemctl does not work, it will simply freeze the computer.

**edit: I uninstalled the SST2 driver as installing it produced more errors and disrupted suspension/sleep. **

I don't know what specific information will help but I will monitor the tread; to start, here is lsmod | grep snd. If anyone has some experience manipulating the drivers for the chromebook pixel LS sound system, including and specifically the bdw-rt5677 device, could you please point me to some resources/ways to understand why I can't get the speakers working?

I forgot to mention-- I am on debian unstable, kernel 5.10.0-7
