Comment 114 for bug 190754

Conn, you're correct in presuming the effect of the fragment settings are highly dependent on audio hardware. (Please note that lspci -v information is insufficient to diagnose; one needs to provide lspci -nv|grep -A1 040[13]. It's the SSID that's important. Or, provide the codec dump in /proc/asound/card*/*codec*.) For that reason, it is not possible to completely resolve the symptoms on all hardware with one set of default fragment parameters.

Marking the linux task fix committed (I'm of a mind to mark the pulseaudio task invalid because of the intractability of all codec&dsp playing nicely with one default configuration).
