Getting audio to work with a VM

Latest response

Hardware: Dell 2950 with no soundcard installed (but open pci-e slots)
OS: RHEL 6.4
VM: Windows Server 2008R2

I assumed, based on my reading of the docs, that I don't need actual hardware to make some real noise inside a VM or am I wrong?

From the RHEL 6.4 docs:

--------------- cut here -----------------
Emulated sound devices
Red Hat Enterprise Linux 6.1 and above provides an emulated (Intel) HDA sound device, intel-hda. This device is supported on the following guest operating systems:

    Red Hat Enterprise Linux 6, for i386 and x86_64 architectures
    Red Hat Enterprise Linux 5, for i386 and x86_64 architectures
    Red Hat Enterprise Linux 4, for i386 and x86_64 architectures
    Windows 7, for i386 and x86_64 architectures
    Windows 2008 R2, for the x86_64 architecture 

The following two emulated sound devices are also available, but are not recommended due to compatibility issues with certain guest operating systems:

    ac97, an emulated Intel 82801AA AC97 Audio compatible sound card
    es1370, an emulated ENSONIQ AudioPCI ES1370 sound card

Can someone point me in the right direction to get working audio out of my Windows 2008R2 VM? Do I need to install a soundcard in the VM host or can this all be done with emulated hardware?

Any help is greatly appreciated.


Are you saying you only tried to hear audio in Windows or did you also install a different OS (eg, Debian) and attempt audio in that system as well? If you can hear audio in Debian but not Windows, then perhaps we can identify the problem more easily. Maybe something is specifically wrong with your Windows configuration, but we don't know to look there yet.
