So, the basic setup is this (excuse my asscii):
[Radeon 7800 HDMI port] ―――――┐
[Xbox 360 HDMI port]――――――[HDTV]――――[Amplifier/Decoder]════[Speakers]
[BD/DVD player HDMI port]――――┘
Now the amp is old and doesn't allow any equaliser presets in anything except stereo mode, which nukes three of the five speakers and disables DTS/Dolby decoding from the Blu-ray player, so that option is out.
However, (like most sub+satellite setups) it's boomy on the bass and slighly weak for midrange warmth by default; I have previously compensated for this slightly by using software equalisers to reduce the sub-80Hz levels and anything north of about 1.5KHz progressively, either with my old Creative drivers or the Realtek sound manager.
Now that I have to run through the Radeon's HDMI port to get picture and sound to the TV over HDMI, I have all audio running through an AMD High Definition Audio Device. The only things I can do with it is Bass management/Room Correction/Loudness Equalisation, none of which actually allow me to edit the treble/bass levels independently.
- Does this mean that the Radeon has a seperate, built-in sound codec as per the realtek on on the motherboard?
- I assume the realtek HD audio is useless, since I'm not using the motherboard SPDIF/Analogue ports?
- Is there any way to get an equaliser (even a simple one) for this AMD HD audio device?
At least, I assume I'm going to have to edit the sound characteristics at the PC end, since the HDTV's audio options are disabled when it's connected to external speakers.
Any help/advice appreciated; I'm fairly fussy about sound quality and speaker quality, but I'm a bit of a n00b when it comes to HDMI audio :\
