-Subject: [PATCH] ALSA: pcm: fix ELD constraints for some compressed audio
- formats
-
-The SADs of compressed formats like AC3 and DTS contain the channel
-and sample rate info of the audio data inside the compressed stream,
-but when building constraints we must use the rates and formats used
-to pass through the stream. eg 2ch 48kHz for AC3.
