I would like to share that I found this post referring to a similar issue where sound settings weren't maintained, maintained being a better word than saved because I believe alsamixer might properly save the settings.
According to the post it is pulseaudio which is actually modifying the settings: http://askubuntu.com/a/549939 I tested as suggested, by modifying the "Headphone Mic Boost" within alsamixer and exiting. I then ran: pulseaudio -k And pulseaudio reset the "Headphone Mic Boost" to dB gain 0.00, 0.00. The hissing reappeared. If I could get pulseaudio to stop resetting the "Headphone Mic Boost" in alsamixer, then that would be an acceptable workaround. But, I think the real issue still needs to be resolved. One would expect a dB gain 0.00, 0.00 to be absolutely silent. The user should not need to kick it up a notch to dB gain 10.00, 10.00. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1654448 Title: XPS 13 9360, Realtek ALC3246, Headphone audio hiss To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1654448/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
