Hi,

Due to lack of time, I didn't update kernel on my desktop system.
Now I notice that analog loopback go removed. Why?


Searching around I found this:

http://article.gmane.org/gmane.linux.alsa.devel/59878

* Removed analog loopback mixer items, not mentioned in sigmatel
datasheets and
  reported to break sound support.


First they are mention. It took me lot of time to find them.
I only have added the loopback items for devices that have this feature in datasheet.

Then how it can break sound support? could you explain?
I need this feature since I use it with my TV card, and I know more users that use that feature.


I don't know about other devices, but I attach the my patch that was included in kernel for this feature.


Best regards,
	Maxim Levitsky
