Over the last couple days all of a sudden any time I change the audio station in the XM radio, the graphics update instantly in the dash and on the infotainment screen, but the audio is delayed by a second or so. Same thing for turn signal. I'll flip on the turn signal which shows the blinker start flashing immediately, but I won't hear the blinker sound until a second or so after.
I found an old random thread about GMC saying to hold down the end call button on the steering wheel for 20 seconds which resets the infotainment system. I did that today and to my surprise it worked.
Just FYI in case anyone else has this issue and comes across this post.
