All your 3 questions are related to ucm, if the kernel uses legacy driver, the pulseaudio will work with traditional profile+path (/usr/share/pulesaudio/alsa-mixer/); if the kernel users sof driver, the pulseaudio will work with ucm (/usr/share/alsa/ucm2/sof-hda-dsp/).
The 3 difference you mentioned are introduced by ucm. Maybe we could make the ucm perfect in future, or maybe the latest ucm + pulseaudio already addressed those issues. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1930188 Title: Acer Aspire 5 sound driver issues To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1930188/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
