[alsa-devel] SoundBlaterX G5

[Milan Oravec]

Hi Clemens,

I'm unable to unload snd_usb_audio module because I can't find module 
locking it.

root at 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 at migo_lenovo:~$ cat /proc/asound/card0/stream0
Creative Technology Ltd Sound BlasterX G5 at usb-0000:00:1d.7-1.1, high 
speed : USB Audio

Playback:

Then I unloaded module with force option and modprobed it again and succes!

migo at 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. ;)

Thank you for your interest and your time.
