I am pretty much a beginner with desktop linux and I recently installed Ubuntu 18.04 on my newly bought Lenovo P51s. Works fine besides a strange sound problem:
- Sound output (internal speakers) is at very low volume and the sound quality is terribly poor (like out of a tin can) when played from Chrome/Chromium, Rhytmbox, VLC, etc.
- But: Volume and quality is fine when played from Firefox
- If any source besides Firefox is already playing sound, sound from Firefox is also bad.
pavucontrolshows same level for all applications. Moving beyond 100% leads to distortion.
alsamixer: all 100%
My audio device is a
aplay -l **** List of PLAYBACK Hardware Devices **** card 0: PCH [HDA Intel PCH], device 0: ALC298 Analog [ALC298 Analog] Subdevices: 1/1 Subdevice #0: subdevice #
Any suggestions? Is this a known issue? What kind of information should i additionally provide?
