Upgrading 12.1 - 12.2 x64 and digital pass through

I just wanted to know if anyone had any problems with digital passthrough when updating from 12.1 to 12.2. I mainly ask because I am hesitant to upgrade because of all the issues I had going from 11.4 - 12.1 and getting my digital audio out working correctly with my receiver. I am using a C-Media 8768 card with digital coax out on it.

After installing 12.2 as an upgrade on my laptop I want to update my desktop but I dont really want the headache that can come from trying to setup digital pass through that Ive had in the past. So just wondering what other peoples experience with this was like. Note that I use alsa not puse (using the xine backend).
