An updated F14 in combination with the GT220 running a recent Nvidia *binary* drivers should output audio onto HDMI just fine with VLC/mplayer/MythTV. What does aplay -l show? There are probably multiple digital interfaces listed, only one will work. On my system with a GT220 aplay -l lists: **** List of PLAYBACK Hardware Devices **** card 0: NVidia [HDA NVidia], device 0: ALC880 Analog [ALC880 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: NVidia [HDA NVidia], device 1: ALC880 Digital [ALC880 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: NVidia_1 [HDA NVidia], device 3: NVIDIA HDMI [NVIDIA HDMI] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: NVidia_1 [HDA NVidia], device 7: NVIDIA HDMI [NVIDIA HDMI] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: NVidia_1 [HDA NVidia], device 8: NVIDIA HDMI [NVIDIA HDMI] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: NVidia_1 [HDA NVidia], device 9: NVIDIA HDMI [NVIDIA HDMI] Subdevices: 1/1 Subdevice #0: subdevice #0 For me the proper HDMI audio I/F is: card 1, device 7. Hope this helps. Jurgen -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
