HDMI audio output hell
This is a gigantic PITA. I can't believe some people still think proprietary software has good support for proprietary hardware - Even with a relatively simple setup like this, many hours of searching forums, installing and reinstalling drivers, fiddling with the BIOS and sound settings still hasn't produced any sound.
- Upgraded the A/V receiver firmware (Update: sorry, the link is dead). This was easy since I've connected it to the Internet. It's now got the latest firmware.
- Installed, removed and reinstalled the latest video driver - Catalyst Software Suite 12.8 (Update: sorry, the link is dead). I rebooted after each step.
- When I plug in the HDMI cable, a device called Generic PnP Monitor is added to the Devices list. I know it corresponds to the A/V receiver, because it is removed again if I unplug the cable. This messed up the dual-screen display the first time I plugged in the HDMI cable, making only the secondary display active until I managed to move the Catalyst Control Center window from the invisible desktop to the visible one.
- Tried to update the driver of the Generic PnP Monitor, but it just says the driver is up to date.
- In the Sound → Playback window the AMD HDMI Output playback device is enabled, but it shows simply Not plugged in, so I can't configure it or set it to the default, as some forum posts instruct.
In the BIOS menu there is a setting called
SPDIF OUT Mode Setting [sic], with possible values
SPDIF and HDMI. It's set to SPDIF, according to
this cryptic description:
Select the [HDMI] option only if you have a video card with HDMI support and are using the SPDIF signal for the high-definition monitor's speakers.I'm not using monitor speakers.
- In the Screen Resolution window there's a TX-NR509 device. The resolution and orientation can't be set, and I've set Multiple displays to Disconnect this display.
- The A/V receiver shows that it's connected, but not receiving a signal.
In conclusion, both devices know about each other, but Windows 7 seems to think the A/V receiver is a monitor. Any ideas?
