Title:
  Logitech Z-5 USB speakers sometimes not detected

Status in Mythbuntu, Ubuntu derivative focused upon MythTV:
  New

Bug description:
  The Z-5 are USB-powered speakers, behaving optionally as a standalone
  external USB audio card (having its audio input through the same USB
  power wire) or as a pair of passive speakers when using a normal audio
  jack.

  First I had to append the following to /etc/modprobe.d/alsa-base.conf
  in order for the speakers to be "properly" detected:

  options snd-usb-audio index=0

  Then the Z-5 seem to be detected by the USB subsystem only after
  alternative reboots/shutdowns, as lsusb command shows. They work
  normally when using a standard audio jack through the MB sound system
  (Azalia), though.

  I shall provide any additional debugging info upon request.
