[MPlayer-dev-eng] Increase alsa buffer size request

[Vladimir Voroshilov]

Hi, All

I'm working on MPlayer radio support (threadless version).
I am using rawaudio demuxer and staff from tv's audio_in.c.
demuxer makes packets with AvgBytesPerSecond length.
In ai_alsa.c and ai_alsa1x.c ALSA's buffer_time is initialized
as 1000000 microseconds.
Thus, when my module is working i get a lot of xrun events.
Is it possible to increase buffer size to 2 seconds or this exact value
is mandatory for tv?
