Subject: cmi8788: add alsa-lib config
X-Git-Tag: v1.0.15rc1~6
X-Git-Url: https://git.alsa-project.org/?a=commitdiff_plain;h=9749c31fa763be9485300e2dd00432f1b4fdee8f;p=alsa-lib.git

cmi8788: add alsa-lib config

Add a .conf file to enable dmix/dsnoop and softvol for CMI8788.

Using dmix helps mask the bug that all audio is forced to 48 kHz. :-)
