Kmixer shows intermittently USB audio mixer(It works,too!)

I am perplexed by the sudden appearance of the USB audio mixer option.

It isn't always present in KMIX.

It has a PCM output volume control 

It has an input option but no input shown.

Does anyone else have the USB Audio option in KDE?

Re: Kmixer shows intermittently USB audio mixer(It works,too!)

I have found a use for the USB mixer in KDE.

If it stays loaded in KDE  KMixer I'll be satisfied.

The trick is to enable XMMS with a .wav selection.  Click on the O option on the left side of the XMMS display: select.....preferences.

Select Output Plug-in ALSA.....

Select ...Configure....
Select under AUDIO DEVICE  ...USB Audio (hw1,0)
Select Mixer Card ...1    and PCM
Click OK

This provided stereo audio from .wav files on the usb Soundwave Optical 5.1 device connected to a USB port on my system while using XMMS.  This device has a stereo output jack and an optical port.

At the same time, another .wav file was possible simultaneously( even the same .wav file) on the PCI audio channel from the normal KDE mixer and PCI card using other multimedia devices(kaboodle, noatun).

I do not have any device for 5.1 surround which is optically provided by the soundwave device(probably not properly addressed for it in the system anyhow).

Maybe this will help someone with their USB audio connect?

Re: Kmixer shows intermittently USB audio mixer(It works,too!)

Finally found the solution....

Moved the /etc/rc.conf entry in modules of ....snd-usb-audio ....to be the first audio related module in the listing.

This provides the.... USB Audio ...mixer option in KDE on boot-up in kernel 2.6.9.

The USB audio is utilized by kaboodle and noatun in my system.  XMMS is now under PCI mixer and the configure options do not respond in XMMS.

Perhaps another change in rc.conf will permit XMMS options to respond.
