AE: Pulse Audio fix buffer underruns.

The cache buffer size was being initialized to the write size
of a PA stream, which is not the buffer size of the PA server.
The cache buffer size will now use the PA server buffer size.

[AE] ALSA: Do not try to bypass dmix for other sample rates

Currently the ALSA sink tries to bypass ALSA dmix when the audio sample
rate is different from dmix sample rate (usually 48000). This is done by
opening "front" device instead of "default" (or "sysdefault").

However, this has the effect that stereo audio is only played on the
front speakers, while "default" device might have routed the audio to
multiple speakers on a multichannel system. This effect is triggered
even on systems that have a hardware mixer and therefore no dmix in the
first place.

To avoid this issue, remove the bypass behavior that was added between
11.0 and 12.0. This change affects stereo audio only as multichannel
audio does not normally have ALSA dmix in the first place.

It would not have been feasible to limit the previous behavior to dmix
systems only, since the ALSA design does not allow us to easily detect
dmix, since user applications should not care about that. If dmix is not
wanted, the user should not have it enabled in the first place.
