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
