f7b262763a alsa: Handle 'Digital Mic' as an 'Input Source' 
BugLink: https://launchpad.net/bugs/533877

Some laptops have 'Digital Mic' exposed as an 'Input Source', e.g., Dell
XPS 1330, so handle these, too.

4df443bbe6 add rewind-safeguard parameter 
Rewinding the ring buffer completely causes audible issues with DMAs.
Previous solution didn't work with tsched=0, and used tsched_watermark
for guardband, which isn't linked to hardware and could become really high
if underflows occurred.

Added separate parameter that can be tuned to hardware limitations and size
of DMA bursts.

7b89c8531c alsa: Cover the 'Int Mic Boost' element. 
This is not 100% ideal as we have not way to tie specific boosts to specific
inputs and this particular chipset (as noted in #772) appears to
support just that.

For the time being incorporate it into the normal boost logic.

53b046d5c9 alsa: disable timer-based scheduling inside a VM 
In virtual machines sound card clocks and OS scheduling tend to become
unreliable, adding various 'uneven' latencies. The adaptive algorithm
that handles drop-outs does not handle it this well: in contrast to
drop-outs on real machines that are evenly distributed, small and can
easily be encountered via the adpative algorithms, drop-outs in VMs tend
to happen abruptly, and massively, which is not easy to counter.

This patch simply disables timer based scheduling in VMs reverting to
classic IO based scheduling. This should help make PA perform better in
VMs.

6839ef6874 alsa: create a seperate mixer path for Speaker elements 
On some cards line-out is independant of Sepaker and it is a good idea
to cover that so that they can independantly be activated.

e63c867f87 alsa: correct assumptions about channels an element lacks 
If an element does not control some channels assume they are 0dB in
comparison to the other elements, i.e. do not influence the volume at
all. Previously we were assuming they were as high as the highest of the
channels we do control.

557c429510 alsa: rework buffer/period configuration 
- As discussed on alsa-devel it's probably better to initialize the
  buffer size first, followed by the period size. If that fails try the
  other way round. If that fails try to configure only buffer size. If
  that fails try to configure only period size. Finally, try to
  configure neither.

- Don't require integral periods anymore.

Both of these changes should help improving compatibility with various
weirder sound devices, such as TV cards.

c1b6a87b27 alsa-sink: reduce the amount of smoother updates 
Exponentially increase the amount of time between smoother updates. We start
with a 2ms interval and increase up to 200ms intervals.
Smoother updates and the resulting linear regression take a fair amount of CPU
so we want to reduce the amount of updates.
