d2a1301073 Make "default" PCM card-specific 
"default" PCM can be card-specific.
The definition is moved to pcm/default.conf, and read on-demmand via
aliases.conf.  The card config can override the default config.

30f35c1f7a Add softvol PCM plugin 
The softvol PCM plugin is added.  It applies the software volume attenuation,
which may be useful for codecs without volume controls.

Currently, the control is only mono.  The attenuation is applied to all
channels equally.  The control is probed and automatically created
when not exists yet.

3a8bfd43d7 Fix the downsampling noise problem 
Description: The patch replaces the nearest neighbor downsampling method
in the sample rate conversion plugin by linear interpolation of the closest
two samples, thus significantly reducing the resampling noise.

6f515096d9 [ALSA-LIB] dmix: dont forget to return -EINVAL on errors 
snd_pcm_dmix_open() returns success if the open fails attempting
to open not the HW plugin (dmix seems to be limited to use only
the HW plugin right now). This leads to memory corruptions and
eventually a SIGSEGV. The attached patch fixes the omission.

6170a88309 Signed-off-by: James Courtier-Dutton <James@superbug.demon.co.uk> 
This patch fixes a number of different bugs in pcm_rate.c.
1) Resampling now works for rate 192000 -> 8000.
2) zero samples are not accidentally inserted into the stream any more.
3) Corrects period size calculations.
4) Prevents avail_min and xfer_align being less than 1.
