[kernel][usb audio class 1] surround channels mapped to wrong alsa channel ids #403

Closed sylware closed 1 month ago

In $linux_src/sound/usb/stream.c, function "convert_chmap", in the "uac1_maps" array, the "left surround" should be SNDRV_CHMAP_RL instead of SNDRV_CHMAP_SL, and the "right surround" should be SNDRV_CHMAP_RR instead of SNDDRV_CHMAP_SR.

kernel patch went thru the kernel sound mailing list.
