Sorry for bumping this, but:
Two problems here!!
(PCM 2.0 only to Logitech z-5500, not 5.1 (3/2)...no dolby digital live option...
(the second one is more serious---how do you get wave files to play, especially repeated windows sound instances, without the sound breaking up, refusing to play or being poppy/scratchy? QUICK AND DIRTY TEST!:
go to control panel ->sound->Asterisk (default windows sound) ,and press "Play" repeatedly quickly.
Notice that the playback doesn't work reliably? it plays, stops, pauses, plays again and has pops.
Proper behavior is stopping the last sound instantly and restarting it... HORRIBLE bug.....while not affecting normal games, this SERIOUSLY AFFECTS the Internet chess club 3.0 blitzin client!! (see below at the bottom)>
Anyway:
TOS LINK (Optical Out) 5.1? How?
How did you get the X7 to output 5.1 to the Logitech Z5500 with optical out?!
The Logitech says "PCM 2.0" even though I have windows set to 5.1
The control panel for the X7 is also set to 5.1.
(it works perfectly in analog mode, but you said in your post you go 5.1 through digital......HOW?)
So...what's going on ?
On the X-fi Fatal1ty, you had to enable "Dolby digital Live" in order to get 5.1 through digital. But there's no such thing on the X7!!
If I click on "SPDIF Out" and do a "Test" on dolby digital (Under properties), the Logitech changes to "3/2 48/16" and all 5 channels play on that test, but after the test is done, the Logitech display says "no optical data" for a second or two, then goes back to "PCM 2.0 stereo".
So....um......someone help?
(there's another problem with windows wave files and sounds not playing instantly or restarting (only wave files) but that's a different issue. But this is ALSO related to the X7, as it does not happen on my X-fi, my USB Beyerdynamic sound dongle or even the realtek in my laptop. This issue REALLY Affects "Blitzin 3.0" internet chess club client really really badly...moving a piece twice fast (in examine mode) won't play the second wave sound (it's supposed to cut off the existing sound and play the second instantly--which it doesn't) and making an "illegal move" plays a laggy, scratchy broken up sound when it should be a normal buzz.
Might have to uninstall and put back my X-fi fatal1ty pci-e, because I play chess a lot...
