I just installed Antergos and KDE from the latest ISO on a Toshiba Portege Z30A. Unfortunately audio doesn’t seem to work, but it worked fine in the Gnome-based live installer.
The audio icon in the tray area has a red circle around it and the tooltip says “Volume at 0% - HDA Intel HDMI - IEC958”. I tried changing the volume level but to no avail. In “Audio Setup” I can see “hda intel pch alc283 analog” as default along with 4 o 5 “cards” flagged as intel HDMI (selecting any of them and clicking the Test button reports failure).
I noticed pulseaudio is not installed but I guess it’s ok… A few things other I’ve tried:
speaker-test reports “unable to open slave. playback open error -2, no such file or directory” (however this also happens in the live installer, where audio works.)
aplay -l shows:
card 0: hdmi 0
card 0: hdmi 1
card 0: hdmi 2
card 1: pcm(alc283 analog) hdmi 2
so I created /etc/modprobe.d/alsa-base.conf and tried to force alsa with: options snd_hda_intel index=1
but it didn’t work.
I’m not quite sure where to look for possible hints as to my problem, so I’d appreciate any assistance.
