Hello alsa team. I'm not sure to write at the right place, so please apologize if i'm being off-topic. I'm using a supposedly standard-compliant soundcard with alsa on linux, and playback is going very fine without issue on the 4 channels.
However, inputs are not behaving well. Captured sound is 'choppy' (like small high pitched discontinuous chunks). After many tries i figured a workaround : if i plug the card to a windows pc, even without using it, it will then capture perfectly from the linux station.
So i suppose the windows driver is doing some initialization. Possibly setting a latency value (i'm supposing that because this value is selectable from the driver tray icon)
As some experts might be on this list, i wanted to ask if you know a way to 'sniff' how the win driver is doing the init. So id be able to replay it with alsactl or custom code ?
Thanks, and sorry again if i'm asking in the wrong place.
Regards, JM

I'm missing patch 1/2 here - what's going on with dependencies?
Hmm, that's strange. I got patch 1/2 and it also appears to be on the mailing list archive.

Maybe it got filtered somehow to another directory inside your email account?
thanks, Daniel. _______________________________________________ Alsa-devel mailing list Alsa-devel@alsa-project.org http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
