I've already commented your bugzilla report, but in addition I'd like to mention that in April I wrote to Rhythmbox-devel mailing list complaining about erratic Rhythmbox behaviour. See http://mail.gnome.org/archives/rhythmbox-devel/2007-April/msg00021.html I later found out that the problem was sound card non-detection if I had my USB headphones plugged in at boot. The problem was already there in FC6. Now that in F7 System->Administration is organized a bit differently I've noted that at least as ordinary user I cannot get my motherboard sound card (NVidia CK8S) detected while F7 is running. The only remedy I know is to boot with USB headphones unplugged - and plug them in only after F7 is up and running. Regards Antti
