As part of a temporary experiment, I put an Nvidia card in my system: 01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [GeForce GT 430] (rev a1) 01:00.1 Audio device: NVIDIA Corporation GF108 High Definition Audio Controller (rev a1) The gnome-control-center sound panel seems to believe that it can output audio to the HDMI output, but nothing comes out on a sound test. If I install the binary nvidia driver from rpmfusion, I do get HDMI audio, so I'm guessing the nvidia driver just can't do audio yet? Another weird thing is that aplay -L lists the built in intel audio S/PDIF: iec958:CARD=PCH,DEV=0 HDA Intel PCH, ALC887-VD Digital IEC958 (S/PDIF) Digital Audio Output But gnome-control-center no longer sees it as an output option, so I can't get audio by going through my receiver either. Any of this sound familiar? (I'll be taking the nvidia card out soon, so I'm not really looking to try and fix any of this, but I thought I'd mention the weirdnesses :-). -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
