[SOLVED]Pulseaudio and ivtv problem

So i have a new Arch Linux install that i have just installed today, i have xorg, lightdm, the proprietary nvidia driver (needed for best performance when i install steam and games) and cinnamon installed. Upon attempting to log into a cinnamon session i only have a black screen with a moveable cursor, i thought for some reason it was slow but even after over 5 minutes of waiting nothing changed. So i logged into another virtual terminal and checked the last 50 lines of dmesg, with that i noticed this stack and call trace with ivtv. Sound was working (tested with speaker-test -c 2) after unmuting the master channel before i installed cinnamon but it probably isn't working now after pulseaudio got installed with cinnamon.

My System has a Intel Quad Core Q6600 CPU, Nvidia GTX 650, 4GB DDR2, and a Asus P5K-SE Motherboard.

I have had Arch installed in the past (at least over a year ago) before alongside Ubuntu, and with the same hardware and don't remember ever having this issue, although i don't remember installing gnome and/or cinnamon so i might have not had pulse installed. i believe ivtv is being loaded for my Happauge PVR 150 capture card.

I am going to try blacklisting ivtv, reinstalling pulse and cinnamon, etc. maybe even reinstalling Arch. But has anyone else had an issue like this before? I really would like Arch
to become my main distro now with Ubuntu dual booted (using now to access this forum).

If this thread is in the wrong place i apologize.

UPDATE: Well it seems simply installing ivtv-utils has solved the audio problem.
