Public bug reported:
Binary package hint: pulseaudio
Playing an ogg file with ogg123 causes underruns (noise), while playing
the same file with sox (play) works fine. In the former case,
pulseaudio uses 10% CPU steadily, vs maybe 1-2% in the latter.
I'm not sure how to diagnose this, but I will attach two 'pulseaudio -v
-v' files for the two cases. These seem to indicated that in the ogg123
case less latency is being chosen (used? requested? planned for?). It
looks to me like both programs are using the alsa interface.
I guess the desired behavior here is for whatever ogg123 is doing to
lead to the same good behavior that sox is getting.
