Title:
ac-53 (a52 plugin) core dumps
Status in “pulseaudio” package in Ubuntu:
Confirmed
Bug description:
This config worked on 13.04
a52.conf:
pcm.a52 {
@args [CARD]
@args.CARD {
type string
}
type rate
slave {
pcm {
type a52
bitrate 448
channels 6
card $CARD
}
# rate 48000 #required somehow, otherwise nothing happens in PulseAudio
}
}
commenting out rate 48000 allows it to work, but stereo only; no
surround.
