> Does using the snd_hda_intel.power_save=0 kernel option makes a

(https://wiki.ubuntu.com/Kernel/KernelBootParameters).

It does not appear to make a difference.

I set usbcore.autosuspend=-1 in the kernel parameters. However I'm not
entirely sure it's fixed the issue, as sometimes it can take quite a
long time to pop up. It has not happened since I disabled it, and have
had about 12 of uptime since.
