ALSA: pcm: Fix the silence data for DSD formats
Right now we set 0 as the silence data for DSD_U8 and DSD_U16 formats, but this is actually wrong. 0 is rather the most negative value. Alternatively, we may take the repeating 0x69 pattern like ffmpeg deploys. Reference: https://ffmpeg.org/pipermail/ffmpeg-cvslog/2014-April/076427.html Suggested-by: Alexander E.
