OSS 4.2 and Mumble

I decided to remove ALSA in replace of OSS. I'm satisfied with everything.... except for one thing. I cannot use my USB microphones in Mumble. After reading around the net, I noticed that the USB functionality in OSS isn't ready, but it seems to be loaded on my system. Mumble has OSS selected as default though, grayed out.

My question is: Is there anyway to get my USB microphone/USB webcam's mic working with Mumble?

Re: OSS 4.2 and Mumble

Try rebuilding the package using the PKGBUILD from ABS with OSS installed.  For some reason the device selection is grayed out when using the binaries from the repo.

Re: OSS 4.2 and Mumble

This is not needed (at least for me). The device selection is grayed out but my mic works fine with OSS and mumble from community.

Re: OSS 4.2 and Mumble

When I rebuilt the package from ABS, I saw that the device selection works correctly (not grayed out.)  It is then possible to select a device other than the default '/dev/dsp'

Re: OSS 4.2 and Mumble

Sweet! That did exactly what you described Splex. Now just to figure out how to get the mics actually working. For some reason, nothing comes through and ossxmix no longer shows both mics.

[dbdii407@myhost ~]$ ossxmix -S
/dev/oss/usb046d0804-0/mix0: No such file or directory
/dev/oss/usb046d0a03-0/mix0: No such file or directory

[dbdii407@myhost ~]$ sudo ossdetect -v
Detected Nvidia MCP51
Detected Generic USB audio/MIDI device (BETA)
Detected Generic USB audio/MIDI device (BETA)
Detected Generic USB audio/MIDI device (BETA)
USB support available in the system, adding USB driver
Detected Generic USB audio/MIDI device (BETA)

I have no idea what I may have done in the past ~ hours for them to disappear from the mixer.

EDIT:
Running the following command got 2 "USB sound device"s containing rec back on ossxmix, i'm assuming they're my USB mics. Still can't hear anything.

[dbdii407@myhost dev]$ sudo ossdetect -d -v
