I'm close to cracking - linphone (0.11.0) keeps coming up with
| INFO1 | <osipua.c: 65> Starting osip stack and osipua layer.
| INFO1 | <udp.c: 112> Entering osipua thread.
MediaStreamer-Message: Found /dev/dsp.
LinphoneCore-Message: Found 3 interfaces.
(linphone:15173): MediaStreamer-WARNING **: oss_card_probe: can't open
/dev/dsp: Device or resource busy.
No! It is *not* busy! I can play audio files with sox & friends happily. All
drivers appear to be loaded:

What gives? The thing is: the sound card is a ES1868, with the ALSA -
drivers as recommended. From what I've read on another location I
understand that duplex on this card is slightly iffy. Interesting enough,
when using another program called ant-phone I can only get it to cooperate
with the card by setting outgoing audio to dsp, incoming to dsp0. The joke
is of course that dsp is a link to dsp0. So to me it somehow looks like a
sound card related issue.
It would be great if someone could fill me in here.
TIA
Andreas
