This gives me /dev/dsp2 (TV card1) and /dev/dsp3 (TV card2) for the two
audio sources. In this case sound is transferd through PCI bus not
through any "external" cable (remember I've got 2 cards in the same PC).
i've got only one card (Hauppauge WinTV [card=10]), but also 2 dsp devices

after a few hours there's only dsp1 left, without any dmesg dsp2 left
for a walk or something.
when i try to get sounds over pci bus
(sox -r 32000 -sw -t ossdsp /dev/dsp1 -t ossdsp /dev/dsp)
it works fine, but its not syncron, it starts with ca. 1/2 sec delay and
everytime i zapp around the delay increase.
one night tv runs the whole night and when i wake up, there's a delay
around 5sec or something.
i've got a K7 1800+ / 512 / Geforce puter, so i think it cant be that,
also i try another interrupt and various kernel parameters noapic,
acpi=noirq, ... but it seems that isnt an interrupt problem.
so i wonder, why others could stream videos and i not :)
Now I can use vlc to capture audio and video from this sources and
stream it through my network.
does anyone got a hint for me ?
best regards
