[alsa-devel] [PATCH] ALSA: hda - Fix missing mute controls for CX5051
by Takashi Iwai 08 Aug '13

08 Aug '13

We've added a fake mute control (setting the amp volume to zero) for CX5051 at commit [3868137e: ALSA: hda - Add a fake mute feature], but this feature was overlooked in the generic parser implementation. Now the driver lacks of mute controls on these codecs. The fix is just to check both AC_AMPCAP_MUTE and AC_AMPCAP_MIN_MUTE bits in each place checking the amp capabilities.

[alsa-devel] [PATCH] 6fire: fix DMA issues with URB transfer_buffer usage
by Jussi Kivilinna 07 Aug '13

Patch fixes 6fire not to use stack as URB transfer_buffer. URB buffers need to be DMA-able, which stack is not. Furthermore, transfer_buffer should not be allocated as part of larger device structure because DMA coherency issues and patch fixes this issue too. Patch is only compile tested.
