Hey guys,

I have a question: is it possible to disable the digital playback device on a sound card? I'm testing an application and it produces a problem only on this kind of hardware (the app is functioning as it should on other PCs with only analog playback devices), so I'm trying to see if this is the issue. Is there any way of disabling this playback device? I've tried muting the S/PDIF PCM in alsamixer, tried upgrading the kernel, but to no avail.

Thanks in advance!
