[alsa-devel] [PATCH] snd-cs46xx: Fix Duplicate front for CS4294 and CS4298 codecs

[Ondrej Zary]

Currently, the Duplicate front control is enabled only for two specific
revisions of CS4294.

Enable it for all CS4294 and CS4298 codecs instead.

This fixes rear output on my VC-4620N sound card
(CS4620 + CS4298 rev.5).
