ALSA Sound Mixer information
What the kernel finds:
[ 9.628766] snd_hda_codec_realtek hdaudioC0D0: autoconfig for ALC3226:
line_outs=1 (0x16/0x0/0x0/0x0/0x0) type:line

[ 9.628775] snd_hda_codec_realtek hdaudioC0D0: Internal Mic=0x12
When I start, I hear a rapid two drum beat from (both speakers I guess). Muting
audio in gdm does not stop this, starting laptop in single user mode, no issue.
Laptop: Dell Precision M6800
BIOS: A14 05/24/2015
Audio Controller: Intel Corporation 8 Series/C220 Series Chipset High
Definition Audio Controller
Can provide additional info, test patches.
Attempted to edit default.pa and added tsched=0 but no change in result.
-> load-module module-udev-detect tsched=0</pre>
