New Revision: 359880
URL: https://svnweb.freebsd.org/changeset/base/359880
Log:
MFC r359355:
Improve USB audio mixer support for USB audio class 1 and 2.
- make sure volume controls are correctly mapped to "pcm" and "rec" depending
on how they deliver audio to the USB host.
- make sure there are no duplicate record selections.
- remove internal only mixer class type.
- don't add software volume controls for recording only.
- some minor mixer code cleanup.
