Using cdparanoia in VirtualBox

Post by MetalSubstance »

Hi all,

Does VirtualBox provide the appropriate virtual drivers for running cdparanoia in a virtual machine? After attempting to run cdparanoia, I get the following error:
Drive is MMC, but reports CDDA incapable.
It will likely not be able to read audio data.
I'm guessing that VirtualBox doesn't provide the ability to access raw CD audio data from a guest.

I'm using an Ubuntu 8.04 guest and a Windows XP host.

Thanks,

I've had a quite look at the source code and the PDM dispatches to one of two internal device drivers: one (DrvMediaISO.cpp) to handle ISO images and one (DrvHostDVD.cpp) which just handles it as a simple block mode device. The only smarts is in working out which (OS dependent) system call to make to eject the device.

I did a quick google on "CDDA MMC CDROM" and found this post quite useful: http://club.cdfreaks.com/f52/what-make- ... om-114478/

Basically whilst both are digital formats the data (MMC) sector format embeds a sync header, sector address and secondary ECC. CDDA is more a simple block mode streaming format, so your error message is correct: the VBox DVD driver is incapable of reading CDDA, so I believe that you will not be able to rip audio.
