Getting chtmax98090 to work with Slackware

[Lysander666]

Hi, thank you so much for your work, I was able to get my chtmax98090 on my Chromebook to work in Ubuntu with no issue whatsoever. However, I would ideally like to get it to work in Slackware.

I copied UCM/chtmax98090 to /usr/share/alsa/ucm which worked fine, killed then reinitialised alsa but killing and restarting pulse then failed [it worked in Ubuntu]. Do you know anything I can do it to get this to to work in Slackware?

Either way, I am very happy to get audio working, you have provided a very valuable solution.

try with a command line to see if the register settings are ok, e.g. # command-line sequence to switch playback/capture # alsaucm -c chtmax98090 set _verb HiFi set _enadev Headphone # alsaucm -c chtmax98090 set _verb HiFi set _enadev Speakers # alsaucm -c chtmax98090 set _verb HiFi set _enadev HeadsetMic # alsaucm -c chtmax98090 set _verb HiFi set _enadev InternalMic Then try to blacklist hdmi-lpe (can't remember the module name exactly), there were issues with pulse audio also remove the autospawn=yes in /etc/pulse/client.conf and see in the pulseaudio -vvv logs what happens. Are you testing on a Baytrail or Cherrytrail chromebook?

Thank you so much for your response - this is a Baytrail. I'll try your suggestions and report back.
