[Alsa-user] Increase buffer size

[Andrew P. <and...@gm...>]

Hi ALSA peeps

I need to increase the buffer size ALSA is using, in order to work around a
problem with my USB audio device, which appears to be caused by something
on my Raspberry Pi. I get occasional pauses in the sound output, which I'm
hoping are just buffer underruns. They sort themselves out once the audio
has been playing for something like 20 seconds.

All my attempts so far to use various conbinations of 'periods'
'period_size' and 'buffer_size' have failed. I'm starting with the
following base asound.conf, which does work:

pcm.ufo202 {
    type hw
    card 1
}

ctl.ufo202 {
    type hw
    card 1
}

How can I get a nice big audio buffer for this device?

Thanks

Andrew.
