Mystery noise/feedback, inhibiting work
I have a recurring problem with ardour (on Ubuntu Edgy's repos)
As soon as I add a track (which connects Ardour to ALSA thru JACK as you know), I have a consistent level of ANNOYING/INHIBITING noise or feedback.
All the JACK connections are correct, my microphone is not to blame, but when I disable the 20dB boost, the noise cuts back to about half level, but its still abnormal.
I had a less severe problem with this before, and it affects new recordings, they pick up the annoying noise.
When I play old tracks, the noise disappears when the track is playing, but when it stops, the noise is there.
I think something is wrong with ALSA, but I can only create this result in Ardour. No other JACK applications suffer from this, and I can't reproduce this in any other audio applications.
I don't think it is user-settings, because both my regular user and studio user suffer the same problem, so all I can picture is a hardware or ALSA problem. Searching has turned up no similar problems from other users.
Can anyone throw me a bone here? Any idea you may have is appreciated, my workflow has ground to a halt because of this nonsense. I need my beloved Ardour!
Cheers, and thank you kindly for any advice! If you need any more info, like my JACK settings, screenshots, recordings, anything, please ask and I will produce. Thanks again
