Hi Clemens,
I'm unable to unload snd_usb_audio module because I can't find module
locking it.
root@migo_lenovo:/home/migo# rmmod snd_usb_audio
rmmod: ERROR: Module snd_usb_audio is in use
Module Size Used by
snd_usb_audio 155648 1
Is there any other way to re-probe sound-card capabilities?
I've changed clock source to direct stereo and stored configuration
(alsactl store) for device. Now, when plugging device in and checking
clock source property is set to direct stereo, but still no 192k.
migo@migo_lenovo:~$ cat /proc/asound/card0/stream0
Creative Technology Ltd Sound BlasterX G5 at usb-0000:00:1d.7-1.1, high

Then I unloaded module with force option and modprobed it again and succes!
migo@migo_lenovo:~$ cat /proc/asound/card0/stream0

Now, when we have proof of concept is it possible to implement this in
driver without this module mess please?
How can I help?
I can provide you with remote access to my computer with sound-card
inserted when needed.
Playback tested and works. ;)

Try unloading and re-loading the driver module (snd-usb-audio).

Clemens
