I don't care at all about frequency - at my age, 44.1KHz is probably just
fine! No, the problem is that I can't even play the 5.1 Dolby Surround
Sound tracks on my DVDs using Apple's DVD player! In the DVD menu, I can
choose different audio formats (Stereo, Dolby 5.1 surround sound) but when
I've selected 8channels in Audio Midi Setup, it just comes out as stereo.
And if I select Encoded Digital Audio, there is no sound at all.
Yes, I know that it is (just) possible to output AC3 encoded signals via
an optical link
(http://www.cod3r.com/2008/02/the-correct-way-to-enable-ac3-passthrough-with-quicktime/
). But this hack doesn't work with the 8channel HDMI option. By the way,
I've tried with and without Perian installed (http://www.perian.org/ ) -
nothing seems to work.
So, let's forget about fancy 7.1 recordings. How about being able to play
the hundreds of thousands of DVDs with Dolby surround sound? Currently, I
have to use a stand-alone DVD player to play them.
It seems to me that having a bit of code built into CoreAudio that can
read AC3 encoded audio tracks and play them through the 8 channels
available via HDMI is the strict minimum.
