avcodec: fill audio frame channel field
Since ffmpeg 4.4 specifying channel layout or channel number is required to call `avcodec_send_frame()` without error. This is new requirement is due to a change in the avcodec internal API brought by 827d6fe73d2f5472c1c2128eb14fab6a4db29032 (ffmpeg repo). They now call `av_frame_ref` which needs the channels fields to be valid. (cherry picked from commit 321a29b0)
