Ardour's too slow / Plugin's going crazy...
I'm using ardour for a while and had no problems installing it, but I still have big problems configuring it.
I run Jack 0.101.1 via QJackctl 0.2.20 on Debian unstable kernel 188.8.131.52 /w realtime patch.
Ardour is V 0.99.2
Desktop Manager is Enlightenment
my pc: 1,4 Ghz Athlon 1 GB Ram, 160 GB UDMA6 HDD
I use jack with realtime priority 60, 44,1khz and 256 frames (latency of 11,6ms says qjackctl, ardour says 5,8ms) with my M-Audio 2496 Audiophile (ice1712 chip).
When I use Ardour, I get after a while the message the Ardour was too slow keeping up with the data flow and looses the connection to Jack. In Jack I get 1-2 Xruns, no other message.
Currently I'm mixing a 10 track mix, which shouldn't be too much for the system. I have to save and restart ardour to fix this, a simple reconnect doesn't work.
At my current mixing state, I have a 44 % DSP load, with buffers at p: 50-99% c:99%
Any idea where this could come from?
The other problem is the freaking plugins... sometimes they go crazy and create feedback which did already hurt my ears and monitors heavily. This is very bad. The TAP Reverberator just freak out and put the channel on about +60db into the read, which my monitors answered with a damn loud unhealthy pop.
The sound was off afterwards, I had to completely restart the jack server. This also happened with GVerb.
Any known issues here? At the moment my sound system work worse than anything I've seen in Windows, because there at least you're hardware doesn't get screwed...
I'm a little desperate, so any advice is appreciated. I'm not too heavily in Linux, code, debugging, bug reporting and on. I'm willing to investigate and spent hours as I did before searching for the problem.
Maybe it's a bit much and I should have split the problems, but just tell me.
Thanks a lot,
