Hi everybody,

can anybody tell me how I can configure jack or arts in my mythfrontend?

To the doc writers: The documention doesn't capture that topic yet.
(Only the point that you should disable such deamons, because otherwise
the alsa devices are not accessible, but that was the time before arts
and jack plugins were in mythtv I think...)

To get closer to my problem, I will give you some output I get. First of
all mythtv is compiled only with arts and jack support (no alsa, no oss).
Starting jack with "jackd -d alsa -S -d hw:0,0" gives:
[...]
creating alsa driver ...
hw:0,0|hw:0,0|1024|2|48000|0|0|nomon|swmeter|-|16bit
control device hw:0
configuring for 48000Hz, period = 1024 frames, buffer = 2 periods

Starting mythfrontend with configured audiodevice JACK:hw0,0 result in
looping:
2006-01-15 13:50:46.268 Error opening audio device (hw:0,0), the error
num was: 7
hw:0,0: Illegal seek
2006-01-15 13:50:46.275 Error opening audio device (hw:0,0),  Port not
found.
hw:0,0: Illegal seek

Both started as root!

Anybody here who can give me a hint?

Second topic arts: Which device name comes after ARTS:...? I only get
this by reading the sourcecode (so also a point for documentation).

Cheers,
Michael
