I'm not sure, what do you mean with "ALSA plug-in" - In Twinkle I'm using
for ringing pulse server and for VoIP audio in/out direct access ALSA
card (2.), which is disabled in PulseAudio (so no conflict).

Another reference app beyond Twinkle I don't use. But Twinkle works very
well (just the call recording is missing). And the audio setting lets
set no just "audio card", but even specific <pcm> defined in .asoundrc
(I'm not using that).

The PulseAudio make me crazy, but uninstalling is not prospective, while
Ubuntu will use it implicitly in future :-/
