It does happen with every ALSA applications I use. I've created
~/.asoundrc as instructed @ http://pulseaudio.org/wiki/PerfectSetup to
be sure everything goes through PulseAudio when ALSA audio is requested.
Most of thse support pulseaudio natively these days, such as SDL. I'm not sure
what the current situation with ekiga is, is it still broken when used with
pulse?
What I did before submitting this bug report is:
- Follow the instructions at http://pulseaudio.org/wiki/PerfectSetup to
create ~/.asoundrc[1]
- Test Ekiga. Uses 100% CPU. Configured to use Default (PTLIB/ALSA)
device.
- With libsdl1.2-debian-alsa installed tested wesnoth for instance,
which relies on SDL, and found it was using 100% CPU.
- Replaced libsdl1.2-debian-alsa with libsdl1.2debian-pulseaudio. This
made wesnoth work seamlessly.
- Re-tested Ekiga. Still using 100% CPU.
I'm aware that SDL now natively supports pulse. I used it for testing
purposes only.
Is there anything else I can try? I've covered everything I can think
of, but am not afraid of further testing if needed.
