audio problem

Post by mimosa »

Six months or more ago I bought an Airtop3, which seems to have a chipset not fully supported by the Linux kernel - see my post here:
viewtopic.php?f=16&t=8301&p=46917

One problem is audio doesn't work out of the box, for which I applied the fix here:
https://fit-pc.com/wiki/index.php?title ... dio#Step_2
Open /etc/modprobe.d/alsa-base.conf for editing
Add "options snd-hda-intel dmic_detect=0" at the end of this file.
Open /etc/modprobe.d/blacklist.conf for editing
Add "blacklist snd_soc_skl" at the end of the file.
However, the sound is rubbish, especially in the bass. I thought it might be hardware (speakers) but swapping them didn't help. I tried using VLC instead of mplayer, but any improvement was marginal. I wonder if the blacklisting may be at fault?

I'm not an expert unfortuneatly, but for sound problems you can try to throw around ALSA and Pulseaudio. Uninstall one, install the other. Reboot maybe then?

That actually worked for me for a while. I dumped PulseAudio and went strictly with ALSA. After all, one application per task!
