[linux]Sound is a no go

(wouter) #21

Just for the statistics.
ALSA brought out a patch for this behaviour (and ET not being able to use sound together with for instance TeamSpeak) together with the sb128pci (es1370 chipset).

The problem is I am quite a noob when it comes to patching sources. But here’s the patch (which you need to patch against 0.9.4 and up):

    }

If someone could point out with which command you could use this patch (maybe a filename to save to would be nice… prolly something like patch.diff or something) it would help some people out there.

(Steltek) #22

patch is probably the most f’ed up utility on Linux, which is saying a lot.

However, I think putting the patch file in the top level directory of your ALSA sources and running

cd /path/to/alsa-X.X.X

patch -p1 -i mypatchfile.diff

may work. Try -p0 if it doesn’t or maybe jump up one directory and try the the patch there. I don’t like patch much, I usually just fiddle until it decides to work (it knows what works and what doesn’t, somehow).

Yeah, it’s pretty crappy tool.
