The only thing I can think of is to compare mmio traces between working and non-working kernels to observe the difference that I seem to be missing. There's a guide at <a href="https://wiki.ubuntu.com/X/MMIOTracing">https://wiki.ubuntu.com/X/MMIOTracing</a> except that instead of tracing the nvidia blob, you need to trace nouveau. Add nouveau to your module blacklist, and boot into text mode. Then start tracing, load nouveau, and stop tracing. (No need to start X.) Collect such a trace file for both a kernel with working hdmi sound and non-working.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
