Update 1.09 does not bring problems. It has caused problems for you. My advice is to re-install the game and update again.
None of this has happened to me and yes, I have 1.09.
Reinstalll Game File in every update
I didn't get the same problems, but it isn't all roses for me. I play GT5 on a racing seat/wheel with a 5.1 stereo mounted to it. This is attached with the standard A/V connection, red and white. For everything else, HDMI goes put of the PS3 into my TV, and optical audio from there to my bigger stereo.
Since this update, I don't get audio through the big stereo anymore, only when I switch the audio (in the PS3 XMB menu) to the av-multi output.
I'd try reinstalling, but the way I use it, it's not an issue.
1) The Music cuts out and its jumpy
2) Cars not loading up when changing cars and in the Garage
3) Installing logo shows up and does not disapear when changing car
4) If you change cars it will freeze so you are stuck so you need to quit
Same here, no problems.
Boyd is your disk dirty because that could cause all of those problems.
