[proaudio] jack is autoswitching output on ICE1712, arghh..

[Michal Žeravík <michalz@xxxxxxxxxxx>]

Hi all inhere,

i'm using Audiophile 2496 on my gentoo64 box with 2.6.16-beyond4.
Alsa drivers are coming with kernel.
There are several types of mixing sound to SpdifOut on Envy24control.
I have digital speakers, but I need to switch SpdifOut to DigitalMix,
otherwise I can hear no sound.
When I start with "jackd -R -P60 -p512 -m -dalsa -r44100 -p16 -n2 -D -Chw:1
-Phw:1 -m -H -M" (version 0.100.7-r3),
everything goes well, but after aprox. 10 minutes
Spdifout is switched on Patchbay/Router automaticly (don't know why)
from DigitalMix to Spdif and I lost sound from jack.
I have to switch buttons manually back to DigMix.
After next 10 minutes again.
Very strange.
Don't you anyone know about this issue?

Thanks in advance.
