I bought a Behringer UCG102 and am trying to get it to work on my son's computer before Christmas. He's running Debian Squeeze. Does anybody have it working on Squeeze? It shows up in alsamixer, but give me a message that "This sound device does not have any capture controls." I'm not sure if that's a show-stopper or not. I was able to use aplay to send output to the headphone jack on the UCG102. I am so far unable to get arecord or rakarrack to get input from the UCG102. I set up jack's input and output devices according to this page: http://varogami.altervista.org/doku/behringer_ucg102_on_debian_squeeze I've tried this on 3 different computers, all with Squeeze installed. I'm currently upgrading a test machine to Wheezy to give that a try. On Squeeze, I was able to use a microphone hooked up to the computer's main sound card, and pipe that through rakarrack. It worked. Any ideas for me? I'm new to rakarrack and jack. Thanks for the cool software! -Rob |

The difference is they show hw:1 being used for input and output. I found I need to have a different one for each, for example, Input hw:1 USB Audio CODEC Output hw:1,0 USB Audio For the UCA202 the only control available in alsamixer is output level, so it doesn't come as a surprise the UCG102 doesn't have any internal controls. My UCA202 works on Debian Lenny, Squeeze and Sid. I think you will get this working if you play around with the selections for input device and output device. A final tip (and I don't know if this applies to the UCG) is I found I had a lot of Xruns on the UCA202 using 44100Hz samplerate, but it runs smoothly at 48kHz. Let us know if you keep having troubles. I'm assuming since you got Rakarrack working with the internal sound card your problem is not likely related to your jack connections. I don't know whether the UCG102 has a "monitor" switch, but if it does, make sure it is disabled. Take care, Transmogrifox |

My experience so far with pulseaudio and jack is that they don't play well together. A good test is to disable pulseaudio. I have not tried it in Debian ( I don't know whether you are using the /etc/init.d/... file, or the userspace stuff). Per Ubuntu ( I have tried this on Linux Mint), you can edit /etc/pulse/client.conf uncomment the line: |autospawn=yes| And change it to |autospawn=no| Then you may need to edit daemon.conf and uncomment this line: allow-exit = yes After saving your changes to the PA configs, then at the command prompt (as your username) me@debian ~ $ pulseaudio -k That should kill it and it won't come back until you manually start it again. If you want to restore things to normal, you can copy the client.conf file to a backup then copy it back when you are done and start pulseaudio. You could also make a script to do this and add it in qjackctl's interface so it automatically changes the config and kills pulse, then starts it again when you stop it. Of course, my suggestion is to # apt-get remove pulseaudio Because I don't think it actually adds much value, and that one line is much easier than tweaking config files ;) Anyway, kill pulseaudio then try starting jackd with the tips I gave you in the last time around and see if things work out better. Pulseaudio has traditionally been a thorn in the side to JACK users. In defense of PulseAudio, there is significant work being done to improve the cooperation between the two, but I don't think you will get those versions packaged in Debian stable (I haven't checked the status of this for a long time, so I don't know whether it is in Sid). I think some people like to use jack as the main audio server that starts at boot time, then use Pulse as a jack client. I don't know how well that works, but something to let rattle in the back of the head in case you go experimenting some day. I hope that helps. Transmogrifox |

Apparently, it was a cabling problem (a 1/8" to 1/4" adapter, to be specific). I had been testing rakarrack using a microphone, because it was easier than sitting at my desk with a bass guitar in my lap. I had a microphone with a 1/8" stereo jack, running through an adapter to 1/4" stereo, and input that into my UCG102. The UCG102 apparently did not like getting a stereo input. So now with a guitar hooked up, everything works fine. I didn't even need to change the jack interface settings from "default" (although I realize I may not always be that lucky). I just open rakarrack, which starts jack, which seems to bypass pulseaudio -- although pulseaudio is still running. All jack connections are made automatically, and rakarrack works fine. I'm glad I don't need to disable pulseaudio. I need it for my LTSP thin clients. Sorry for the noise. Thanks a lot for your quick responses, though. And thanks for the software! -Rob |

FWIW A microphone 1/8" jack is typically not stereo. The problem is most computer mics (or mics that generally have the 1/8" jack) require a bias. The Microphone input provides a DC voltage to power the active preamp built into the microphone element. |
