Ilia Mirkin <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Summary|No HDMI Audio out |[NV4B] No HDMI Audio out |(pass-thru) on Geforce 7600 |(pass-thru) on Geforce 7600 |Go |Go --- Comment #2 from Ilia Mirkin <[email protected]> --- There is only HDMI audio support starting with NV84. If you're interested in helping to get this to work, please collect a mmiotrace of the nvidia proprietary driver that captures a plug and unplug HDMI event. (i.e. start it without hdmi, then plug hdmi in, then unplug it.) Please be sure to add trace markers (echo stuff > /sys/kernel/debug/tracing/trace_marker) before/after you perform each of those things. I guess it wouldn't hurt to also try playing something over HDMI, but I doubt that anything actually happens when you do that. [Please make sure it's an audio-only thing, as video would rather complicate the trace.] There are some instructions on how to do an mmiotrace at https://wiki.ubuntu.com/X/MMIOTracing The resulting trace file should be 50-100MB, so please compress it before uploading. (And if it's just a few KB, you did something wrong.) Also upload a copy of your vbios (/sys/kernel/debug/dri/0/vbios.rom if you're running nouveau). -- You are receiving this mail because: You are the assignee for the bug.
