Hi guys, We need to sort out Mixxx's problems with PortAudio because it's destroying our user experience on Ubuntu. We have a few major problems to deal with:
1) The non-mmap patch in PortAudio apparently causes random hangs with ALSA: https://bugs.launchpad.net/ubuntu/+source/portaudio/+bug/383431 2) Ubuntu's PortAudio package lost support for JACK a few distributions ago, and it's still not back: https://bugs.launchpad.net/ubuntu/+source/portaudio/+bug/360590 3) Some soundcards require the magic plughw:### device to be opened instead of hw:### with ALSA. PortAudio has a workaround to default to doing this if you export the PA_ALSA_PLUGHW=1 environment variable before you run Mixxx. So far, what we need to do is: 1) Email the PortAudio mailing list about the first item. I want to know if anyone else has seen these random hangs with ALSA + the non-mmap patch. I will do this shortly. 2) Ubuntu/Debian packagers! Can you please help us out with these? We're working to get Mixxx 1.8 out and packaged before the next Universe freeze, and our users would be ecstatic if we resolved these issues. Is JACK included in main yet? 3) Can I please get some testers to run Mixxx with that PA_ALSA_PLUGHW=1 env var set and let me know if it affects their latency in any way? (Make sure oyu tell me what soundcard you have too.) Does anyone know why we shouldn't default to running with that set? Any comments or help anyone is able to provide would be greatly appreciated by both our development team and our user community.
