i am a little uneasy about filing this in mantis, because it is hard to
if i load an existing session (made with beta29) into ardour i sometimes
get no sound or only some crackling noises from specific tracks.
Furthermore i sometimes have the "play"- function in the
Import-Audio-Dialogue pumping up the gain to more than 200 db (at least
the meter of the masterchannel says so...), this happens if i:
1.) hit the play-button
2.) push again to stop
3.) push once more immediately to play the same file
after this envy24control shows an over-the-top level and in about 2 of 5
cases alsa refuses any Jack-clients to play audio (even if the Meters of
Ardour are in the green).
I made up a complete new session for witch i imported some stereo-wav
files, edited/mastered with rezound 0.9, 44100/16 standard-wav-format.
No extreme behaviour so far but also unbearable crackling noises and
occasionally some strange distortion that reminds me of artifacts as
produced by the time-streching-tool (if overused).
1.) is there anybody else out there experiencing something like this and
is there a workaround?
2.) could this be an issue with alsa and/or with its ice1712-driver?
188.8.131.52-20a-default i686 i386 GNU/Linux
alsa 1.0.9-91 ice1712 / envy 24 /terratec ewx 24/96
jack is started like this:
23:20:06.128 /usr/local/bin/jackd -dalsa -dhw:0 -r44100 -p512 -n2 -s -H
23:20:06.132 JACK was started with PID=17490 (0x4452).
besides: beta30 looks most promising :-) thank you all - great Job!!
Alles Gut, bis bald
