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
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.
lspci lists the following for the device:
02:00.0 USB Controller: Teradici Corp. Device 1200 02:00.1 Audio device: Teradici Corp. Device 1200
