I installed Manjaro KDE on the Razer Blade Stealth Early 2020 (
inxi here), and as per the recommendation on the Arch website I upgraded the kernel to 5.6 / 5.7 (tried both).
Most things work fine after a little bit of tweaking, but I noticed that no sound card is detected by default, so there's no way to play any sound or record any audio. The card however is certainly recognised in
Audio: Device-1: Intel Smart Sound Audio vendor: Razer USA driver: sof-audio-pci bus ID: 00:1f.3 Sound Server: ALSA v: k5.6.15-1-MANJARO
After some digging around. I managed to get a workaround going by changing to the
HiFi PulseAudio profile:
pactl set-card-profile 0 HiFi
and I also got the corresponding setting going on
/etc/pulse/default.pa. So now I can hear stuff, awesome! Once I tried to join a meeting on my browser however, I noticed that the browser doesn't detect any microphones... in fact it doesn't detect any audio devices at all (even though the test ping still works):
At this point the problem I'm starting to feel lost... would anybody here mind giving me some troubleshooting advice? Thank you so much in advance!
Edit: in the configurations page of
HiFiprofile is listed as "unavailable", and selecting it will lead to the iffy audio behaviour described above:
I simply switched back to Kernel 5.4 and this seemed to have taken care of the issue. This allows Analog output to work but the browser issue is still present, so we're still stuck.
Jun-10: Solved! Turns out this is an issue of Intel SOF, which is relatively new technology and isn't robustly supported on Linux yet. Solution took a lot of digging and I probably wouldn't have figured it out without very specific hints the Linux masters (credit alphazo on Arch forums).
