[alsa-devel] [PATCH 0/3] Auvitek au0828 fixups

[Mauro Carvalho Chehab]

Testing auvitek au0828-based devices with xawtv caused lots of overruns,
as the period_bytes is set to a too low value, with causes troubles
when syncing the audio capture from au0828 card with the audio playback,
at the main audio card.

It turns that we need a period_bytes size that it is big enough to receive
data from two consecutive URB intervals.

While here, also add the missing USB IDs from other au0828-based devices.

Mauro Carvalho Chehab (3):
  sound: Add a quirk to enforce period_bytes
  sound: simplify au0828 quirk table
  sound: Update au0828 quirks table
