Hello list
Since some weeks I test AC3 on top of pulseaudio-0.9.15 from git . This
works mostly well if only one stream is running at a time. After a
second stream is mixed in, the output begins stuttering. This is all
without the new glitch-free mode.
I tried to use glitch-free mode with linux-2.6.28 and realtime
scheduling enabled on alsa-lib 1.0.19 + alsa-plugins-1.0.19 .
But that doesn't work with a52. Pulseaudio gives this:
D: alsa-sink.c: snd_pcm_avail: Broken pipe
D: alsa-sink.c: snd_pcm_avail: Buffer underrun!
I: alsa-sink.c: Starting playback.
I: (alsa-lib)pcm_hw.c: SNDRV_PCM_IOCTL_START failed
D: alsa-sink.c: Cutting sleep time for the initial iterations by half.
D: alsa-sink.c: snd_pcm_avail: Broken pipe
D: alsa-sink.c: snd_pcm_avail: Buffer underrun!
I: alsa-sink.c: Starting playback.
I: (alsa-lib)pcm_hw.c: SNDRV_PCM_IOCTL_START failed
and so on forever.
The pcm is setup like this:
pcm.a52 {
type a52
@args.0 {
type integer
default 0
}
}
So the question is, is it planned to get the a52 plugin working with
pulseaudio and glitch-free? Or can I do something other to get it at
least working without glitch-free? Any ideas how this can be improved?
Thanks in advance
