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.

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". However, it looks like the onboard sound has been disabled by the KVM card.

The only entry in /dev/snd/ is pci-0000:02:00.1, which is the audio interface on the KVM card (see lspci output below).

• Where can I select to use the onboard audio instead of the KVM card?


• 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.
