Does anyone have any experience with the A52 plugin? I've compiled the
plugin 1.0.14 and installed it.
When I attempt to upmix a 2 channel mp3 to 6 channel through spdif, the
audio plays, but it's choppy. I get a few seconds of audio, then a few
seconds of silence, rinse and repeat.
~/.asoundrc has ...
pcm.!default {
type plug
slave.pcm "iec958"
}
pcm.a52encode {
type a52
}
pcm.stereoupmix {
type upmix
slave.pcm "a52encode"
channels 6
}
I'm testing with mplayer -ao alsa:device=stereoupmix some.mp3
I get this message the stdout.
