    Yes, of course!

    To see what has changed, I'll need two dumps: one from GOOD 3.3.7 and one from BAD 3.4.0.

    1) Install "radeontool" [0] tool in 1.6.3 version (or newer), it will provide 2 important tools: radeontool and avivotool.
    2) Start playing audio with 3.3.7 or 3.3.8 and do: "avivotool regs hdmi > good.txt"
    3) Start playing audio with 3.4.0 and do: "avivotool regs hdmi > bad.txt"
    4) Please attach both files to the bugzilla report

    3.3.7 works fine. In kernel 3.4, the HDMI audio device is correctly found. But no sound is coming out (I've tried aplay with correct device number, try to unmute and all didn't work).

    OK. In case of real problems really helpful will be dump of HDMI regs from both kernels: 3.3 and 3.4. To make a dump, start playing audio and do "avivotool regs hdmi" (as root).

    The one you prefer

    Heard that 3.4 give a performance boost for radeon driver, however, I can't use it unless HDMI audio is also working.
    I can't see any HDMI/audio change between 3.3 and 3.4. Are you sure you use radeon.audio=1 for both kernels? If so, please create bugzilla report, I hope we'll solve this.

    Thanks for the quick reply! Too bad for me then, I can't imagine an easy solution for this problem...
