44fb7aae82 [ALSA] oxygen: remove MIDI autodetection
The MIDI bit in the MISC register is set by default and cannot be used
to detect the presence of a MIDI port.  Instead, add a parameter to the
oxygen_pci_probe() function so that model drivers can specify this.

28a0d9df07 [ALSA] hda-intel - Make azx_get_response() a bit more robust

It's better to be checked just after the check of the RIRB index to avoid

f4beee9420 [ALSA] hda-codec - Fix capture source for Cx5045 codec
For codec conexant 5045, I found that the name of 'Capture Source Items'
is different from the name of mixer.
The mixer is:
HDA_CODEC_VOLUME('Ext Mic Playback Volume', 0x17, 0x2, HDA_INPUT),
HDA_CODEC_MUTE('Ext Mic Playback Switch', 0x17, 0x2, HDA_INPUT),
But the capture source item is :
static struct hda_input_mux cxt5045_capture_source = {
	.num_items = 2,
	.items = {
		{ 'IntMic', 0x1 },
		{ 'LineIn', 0x2 },
	}
};
I think that it's better to change the name of capture_source to avoid
misunderstanding.

52987656fb [ALSA] hda-intel - Add workarounds for STAC codecs
Some machines with STAC codecs seem to have problems (e.g. no audible

I still don't figure out which command sequence causes this problem
(due to lack of test hardware), but it's known that increasing the
delay fixes.  So, added a stupid workaround here temporarily...

e70515dd51 [ALSA] snd-powermac: handle dead DMA transfers
This patch provides the snd-powermac sound driver with the ability to handle
dead DMA transfers. If a dead DMA transfer is detected, the driver now sets
up a new DMA transfer to continue with the sound output at the point where the
old transfer died.
This dead DMA transfer handling has become necessary with recent kernels on
certain G4 PowerMacs. Please refer to the following URLs for more information:
 https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3126
 https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/87652
 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=436723
The patch is based on the dead DMA transfer handling code from the old dmasound
driver which can be found in the file sound/oss/dmasound/dmasound_awacs.c in
the Linux source code.

8c12158687 [ALSA] PCM interface - rename SNDRV_PCM_TSTAMP_MMAP to SNDRV_PCM_TSTAMP_ENABLE
Change semantics for SNDRV_PCM_TSTAMP_MMAP. Doing timestamping only in
the interrupt handler might cause that hw_ptr is not related to actual
timestamp. With this change, grab timestamp at every hw_ptr update to
have always valid timestamp + ring buffer position pair.
With this change, SNDRV_PCM_TSTAMP_MMAP was renamed to
SNDRV_PCM_TSTAMP_ENABLE. It's no regression (I think).
