Hello all,

I have just installed Trisquel 5.5 64bit on my HP DC7800P SFF, and installed all the updates. Everything has gone well with this system except I have one issue. The graphics card I am using is an NVIDIA Geforce 210 which has HDMI out for sound and video, and I use DVI instead of HDMI. My motherboard also has integrated audio, which I normally use for sound (I've used this no problem in the past with other GNU/Linux distros). However, every time I boot into the system, despite me changing the settings in the BIOS to disable the sound output in the graphics card and use the integrated audio instead, it always disables the integrated sound and uses the sound from the graphics card instead. This means I cannot get sound unless I use HDMI, but HDMI gives terrible picture quality on my monitor. Here is the output of lspci:

As you can see, the only soundcard lspci detects is the NVIDIA one, and the integrated audio is an Intel HD Audio controller, which is listed as supported on h-node.

I'm not sure what caused this problem, so if anyone could help me, it would be great. :-)

TIA,

What about physically removing the nVidia card? Not only you will have the sound passing through the Intel chipset but you will save energy and may even have better graphical performance (Intel graphical chipsets being perfectly handled by Linux-libre, unlike nVidia's)!

If removing the card is an option I'd 2nd that. Intel's drivers are comparable to the low end of NVIDIA offerings these days. They actually offer better support in some areas from a features perspective.

And if you don't want to remove the card (which I agree would be your best option), use .asoundrc

Have you tried PulseAudio Volume Control (is the package pavucontrol installed)?
