id summary reporter owner description type status component version resolution keywords cc guest host 3494 Audio CDs are not recognized => enable passthrough option Werner Donné I have a Mac OS X 10.5.6 host with a Windows XP SP3 guest that has the guest additions installed. When I insert an audio CD it is visible in Windows Explorer, but it is not recognized as an audio CD. It says the format is unknown. There is no copy-protection on any of the CDs I tried. When the Passthrough option is on, which is normally only for writing, the CDs are recognized as audio CDs, but when opening them Explorer hangs. Windows Media Player would then show the album title, but is not able to play the CD. defect closed audio VirtualBox 3.0.8 fixed audio cd other other
