Re: hdmi audio only working once (per boot) after upgrading from 256.53 to 260.19.29
I have exactly the same problem!
If I restart X, the HDMI audio will stop working. I will get sound back only after a reboot.
I'm running Archlinux on a Asus M3N78-VM equipped with a GeForce 8200 (MCP78S).
Kernel 2.6.37, NVIDIA drivers 260.19.36.
