Enable unmute/mute amp notification. This doesn't seem to affect HDMI support so this is done unconditionally.
An earlier version of this patch set a chicken bit at address 0x62F38 prior to the mute/unmute but this register doesn't seem to do anything so this phase was removed.
Sorry, this seems like a wrong result. It worked yesterday, but when I retested the latest code today, it didn't work any longer. Then, after setting the chicken bit, it starts working again.
But now I can't make it broken again. Turn off the monitor, turn off the machine, DPMS off, suspend/resume... All still works without chicken bit set.
Also, the chicken bit of the register 0x62f38 couldn't be read back. The register always returns zero when read.
The docs do say it's write-only actually.
OK, thanks for confirmation!
