I configured empeg-preinit v3 etc. manually and also had this problem in-car so it's probably not a problem with genixia's shell script as such. FWIW, at the time I would have been running 2.0b11, pre-init v3 & Hijack 276.

It only occured during one 'sitting'. Pulling the player from the sled didn't make any difference and (AFAICR) I had to select Player as the music source to get rid of it.

That was earlier this week and was the first (and last) time it happened.
