Hello, Further to my previous mail on this topic... If I cross-compile the pjsip stack, things still break. So I tried installing a new rootfs image with native toolchain and rebuilding pjsip natively. The configuration stage now seems to think there's no alsa support and after building (~2hours!!) the code runs and hooks up to audio successfully! OK, so the sound quality is crappy (seems to pulse in volume between normal and off at a fastish frequency, say 5-10Hz or so), but it's progress. Upshot is that I now *think* I have a problem with the alsa modules not being loaded by the kernel properly rather than having a problem with the pjsip stack per-se, so I'll go and bug the people at OE / Angstrom instead. Thanks, John Martindale P.s. I'd be perfectly happy with the OSS version if anyone can tell me how to sort out the audio quality easily. :-) Practical Control Ltd 448 Brightside Lane Sheffield S9 2SP T: 0114 2561888 F: 0114 2617052 www.practicalcontrol.com <http://www.practicalcontrol.com> Registered in England: 4117809 This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
