I recently freshly installed Ubuntu Studio Gutsy on a machine w/ Asus mobo, Intel onboard sound (fancy surround outputs etc. but I can't vouch for quality), and am running the realtime kernel.
Regular system sound has always worked fine, but I haven't been able to get Jack-based sound working right yet. I'll fire up the Jack Control and start Jack, then run Creox, Ardour, or both, and plug a guitar in (usu. through a pedal, sometimes straight in). Through my speakers, I can hear the clean (or otherwise) line-in sound just fine, but no matter what I try in a mixer, Jack's connections and settings, Creox's settings, or Ardour's settings, I cannot get that line-in input processed--Creox doesn't mangle it and Ardour doesn't record it. But if I reach over and plug the input into the computer's mic input instead, it works, noisily--& there's an annoying noise-gatey effect, like mic voice activation or something, in Creox (not an intentional effect as far as I can tell), and whatever's causing that, I really I ought to be able to use line-in too. This seems tantalizingly close to sounding like an audio port configuration change of some kind, but I'm just clueless enough not to know precisely where to prod in Linux. Does this sound like a symptom anyone else has had? Jack settings, not that this will help if it's an audio hardware config thing, are as follows: realtime soft mode priority = 0 frames/pd. = 1024 sample rate = 48000 periods/buffer = 3 port max = 256 timeout ms = 500 interface = default dither = none audio = duplex input device = default output device = default input channels = 2 output channels = 2 input latency = 0 output latency = 0 (I'm showing latency of 64ms, but Jack goes xrun crazy on me if I don't select soft mode, and it's the best I've been able to do so far, unfortunately.) Hardware wise, I'm showing, under High Definition Audio Controller, ALC880 Analog ALSA Capture Device ALC880 Analog ALSA Capture Device HDA Intel ALSA Control Device ALC880 Analog ALSA Playback Device ALC880 Analog OSS Control Device ALC880 Analog OSS PCM Device ALC880 Analog OSS PCM Device and in Creox's Jack settings, I'm showing alsa_pcm:capture_1 alsa_pcm:capture_2 alsa_pcm:playback_1 alsa_pcm:playback_2 which are what show up as capture_1 capture_2 playback_1 playback_2 in Jack's Connections window under alsa_pcm along with input & output entries for Creox. So it seems like all the elements I'd expect are there. I apologize if this is a hardware and not U.Studio issue; haven't heard a peep on the Ubuntu forums.
