Default Re: hdmi audio only working once (per boot) after upgrading from 256.53 to 260.19.29


I stepped over this thread - although its already old, nothing has changed: Im facing exactly the same problems the others already have described.

My machine is used as a multi-purpose machine (VDR, xbmc, router, fax-machine, homeserver), and i usually switch off X to save energy while noone uses the output. This does not work with any driver >= V260.

For all drivers >= V260:
* sound over HDMI is working exactly once after a reboot
* if I try to restart X, im losing sound permanently until I reboot the machine

* if I stop X and exchange the driver by an old one (V195 or V256) WITHOUT rebooting, im getting back sound.
(This does not work for any Driver >=260, swapping the driver back to one of these Versions still requires a reboot to get sound working again)

My Mainboard is an Asus M4N78 Pro / integrated nVidia Chipset:
00:07.0 Audio device: nVidia Corporation MCP72XE/MCP72P/MCP78U/MCP78S High Definition Audio (rev a1)
02:00.0 VGA compatible controller: nVidia Corporation C77 [GeForce 8300] (rev a2)

System: Debian Squeeze x64 / Vanilla Kernel, currently V2.6.35.14

I tried the following Driver-Packages:

WORKING as expected, sound is working perfectly no matter how often i restart X:

sound is ONLY working exactly once after a reboot:

With still a little hope this will be fixed once even after those mainboards are deprecated
