mixxx and jack, horrible sound playback
I built the latest svn of mixxx with the portaudio snapshot (for jack support) and sound playback is horrible. It has a crunchy digital delay sound. If I raise my frames/periods to 1024 (latency ~48ms) it sounds clear. This is true for my built in intel AC97 and usb M-Audio fastrack pro. Both of which, I used successfully in the past, using this same hardware. I recently installed ubuntu studio (installed from dvd). Do you think this is the issue? Has anyone experienced this on ubuntu studio? I posted to both lists just in case...

Audio-Visual Installation Question
Hi List, I'm setting up an istallation that consists of: 1) Visual: A 30 minute Video File on playback 2) Audio: Live manipulation of sound samples with Audacity/Ardour to accompany the Video. I own one laptop (Ubuntu w/ VIA/S3G Graphics Card) and one Toshiba TDP-S8UK projector. The question is: How do I project the video while doing my real-time Sound improvisation using only the two pieces of Hardware that I own? I have come up with a few ideas, most of which require extra hardware (e.g a cheap DVD player to connect to the projector while I dedicate my laptop to Audacity). I've also been thinking whether it would be possible to 'split' the screen in half somehow - left part of the screen being sent to the projector whereas I use the right part of the screen for Audacity/Ardour. I appreciate that this list is not ideal for this type of question but it's the most relevant I am aware of!

Freebob problem with FireWire Solo
Hi all. I need some help getting Freebob to work with Ubuntu Gutsy. I'm trying to use my new M-Audio Firewire Solo device instead of a soundcard. When I run gscanbus, the Firewire Solo is recognised, but when I do $ aplay -l I get the message: aplay: device_list:204: no soundcards found... However I know that the Jack server can 'see' the Firewire Solo in some way because if I do $ jackd -d freebob without the Solo plugged in, Jack won't start. But if the Solo is plugged in Jack will start, and I get the messages: JACK compiled with System V SHM support. loading driver .. SSE2 detected Freebob using Firewire port 0, node -1 libiec61883 warning: Established connection on channel 0. You may need to manually set the channel on the receiving node. libiec61883 warning: Established connection on channel 1. You may need to manually set the channel on the receiving node. But still I don't get any sound. I have no idea what 'manually set the channel on the receiving node' means. Also, I don't know if this is meaningful in any way, but when I open qjackctl and go to setup, the 'input device', 'output device', 'input channels', and 'output channels' drop-down boxes are greyed out. I've read all the info I could find on this from Google searches (though a lot of it is way over my head) and I'm running out of things to try to make this work, does anyone have any ideas?
