Here's some behavior I've never seen before:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=247224
My motherboard's CK804 audio system utterly vanishes if I have the webcam plugged in at boot time :-).
Doesn't have anything to do with the highly alpha uvcvideo driver I was playing with because I found it fails even if the uvcvideo driver isn't installed. Apparently it is something about the USB microphone component of the webcam that gets linux confused at boot time.
Anyone ever seen a USB device hide a non-USB device like this?
Hi Tom,
someone has. 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
