[Touch-packages] [Bug 1654448] Re: XPS 13 9360, Realtek ALC3246, Headphone audio hiss
It looks like there was some activity with a kernel patch from someone at canonical at some point: https://patchwork.kernel.org/patch/9128611/ -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1654448 Title: XPS 13 9360, Realtek ALC3246, Headphone audio hiss Status in alsa-driver package in Ubuntu: Confirmed Status in pulseaudio package in Ubuntu: New Bug description: Pertaining to 16.04 on a dell XPS 13 9360 ii alsa-base 1.0.25+dfsg-0ubuntu5 Advanced Linux Sound Architecture Driver Version k4.4.0-57-generic. When headphones are plugged in, there is a clearly audible hiss (white noise). This is present as soon as the headphones are plugged in, whether 'headphones' or 'headset' are selected from the pop-up box. Using alsamixer to debug the issue reveals that it is related to "Headphone Mic Boost" - the default setting is: dB gain 0.00, 0.00. If this is changed to: 10.00, 10.00 (one notch up) the hiss disappears. 20.00, 20.00 cause a louder hiss and 30.00, 30.00 causes an even louder hiss with high frequency audio artifacts. When the headphones are removed and plugged back in the Headphone Mic Boost setting returns to dB gain 0 and the problem also returns.

This bug is pretty obnoxious... So far the only way I've found to get the alsamixer settings to persist without pulseaudio repeatedly undoing it is editing the pulseaudio config files per the arch wiki here: https://wiki.archlinux.org/index.php/Dell_XPS_13_(9350) Hissing/Crackling noises when using headphones section Unfortunately this disabled the internal mic completely though and the changes will get reset when pulseaudio is updated. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1654448 Title: XPS 13 9360, Realtek ALC3246, Headphone audio hiss Status in alsa-driver package in Ubuntu: Confirmed Bug description: Pertaining to 16.04 on a dell XPS 13 9360 ii alsa-base 1.0.25+dfsg-0ubuntu5 Advanced Linux Sound Architecture Driver Version k4.4.0-57-generic.
