RE: Cannot install or boot due to out of space errors
The default kernel logging for some pcie devices generates a lot of events which I believe caused the root partitions to fill up when performing an install or a live boot. Before you can install Ubuntu onto this system you need to use the pcie_aspm=off kernel option to suppress the events.
RE: Microphone not picking up sound
Edit the /etc/pulse/default.pa to include load-module module-alsa-source device=hw:0,0 before the .ifexists module-udev-detect.so line.
Also, I had to write a small script in /usr/local/bin that is invoked by a systemd module at boot time to ensure that the audio levels were correct, the script contained the following commands:
Code:
hda-verb /dev/snd/hwC0D0 0x1a SET_AMP_GAIN_MUTE 0x5003
hda-verb /dev/snd/hwC0D0 0x1a SET_AMP_GAIN_MUTE 0x6003
hda-verb /dev/snd/hwC0D0 0x23 SET_AMP_GAIN_MUTE 0x5200
hda-verb /dev/snd/hwC0D0 0x23 SET_AMP_GAIN_MUTE 0x6200
hda-verb /dev/snd/hwC0D0 0x08 SET_AMP_GAIN_MUTE 0x503f
hda-verb /dev/snd/hwC0D0 0x08 SET_AMP_GAIN_MUTE 0x603f
hda-verb /dev/snd/hwC0D0 0x08 SET_POWER_STATE 0
hda-verb /dev/snd/hwC0D0 0x1a SET_POWER_STATE 0

I may find some other quirks and will try to add it to this forum.
