I have a Dell Precision server with a PCIe FX100 KVM Host card installed (manufacturer is Teradici but it's rebranded as a Dell solution.)
I am not using this card (it's installed in the machine but not externally connected to anything), but I believe it's still overriding the onboard audio to be the default, and only, audio output. As such, the audio from the server is being routed to the KVM card. I do not want this to happen as I have speakers connected to the audio out jack.
I'm running Ubuntu 10.04, and under System -> Preferences -> Sound, the only thing listed is "HDA Teradici", which is the KVM card.
According to the server's manual, the onboard audio is supposed to be "an integrated two-chip audio solution comprised of Sigmatel’s STAC9200 High Definition Audio CODEC and the ESB2’s integrated AC97/High Definition digital controller".
- Where can I select to use the onboard audio instead of the KVM card, or how can I find where the PCI card is overriding the onboard sound?
- If that's not possible, is it possible to disable the PCIe KVM card somehow? This is a remote machine so I'm not able to physically remove the card.
I would also appreciate any troubleshooting steps to point me in the right direction for where this card may be overriding things, any relevant logs, etc.
lspci lists the following for the device, but does not appear to list any other audio devices (using
lspci -v | grep Audio):
