-Subject: [PATCH] bcm2835: add fallback channel layouts if channel map API is
- not used
-
-Should be more useful than just forcing stereo.
-
-We can't match the exact legacy ALSA channel layouts, so this is a
-"best effort" hack.
-
-I'm not sure what happens if the application requests channel counts
-that are not power-of-2s. The channel map API hopefully forces
-applications which use the channel map API to request the correct
-count by adding padding channels, but the bare API enforces
-nothing. Possibly this could be added to rate_hw_constraint_channels
-at a later point.
