Did you disable the on-board audio, in the bios?
Did you connect the optical cable to the STX's optical connection or the motherboard's optical connection.
In the Windows control panel, in the "sound" section, in the playback tab, you did leave it on "Speaker" Asus Audio device?
In the Asus Xonar Control panel, did you enable S/PDIF Out ?
If you set S/PDIF to PCM, you get two channel (uncompressed) digital audio, if set for DDL (Dolby Digital Live) for up to 6-channel of compressed audio.
The PCM setting is fine for 2.0 or 2.1 Yamaha speaker setup.
Did you go into the Yamaha's setup, make sure the optical input port you plugged into is properly enable?
Yes I disabled on board audio
I connected the opitical to STX and reciever
It is currently on S/PDIF Asus Audio Device in "Sound" Section, in the playback tab
Where in the Asus Xonar Control panel do you enable S/PDIF out?
Yes the Yamaha setup is correct.
The problem I have now is that the speakers seem to be bypassing the soundcard completly. The Xonar audio center does not recognize that the speakers are working. Im new to good speakers so I cant really tell if they are not playing at max quality but when I plug in my headphones they for sure are playing at a diminished quality. I cannot change the khz or audio channel or control the speakers at all through the Xonar Audio Center. The headphones only work correctly when I change the defaul to speakers under sound/playback, and then the speakers and reciever as a whole doesnt seem to work (when under sound/playback/speakers as default the headphones only work when connected directly to the soundcard. When connected to the reciever they dont work at all and neither do the speakers themselves). The speakers only work when I set up my sound/playback/S/PDIF as default and put PCM on Xonar Audio Center.
So the problem is that I cannot use both my headphones and speakers unless I change around a bunch of settings for each use of either headphone or speaker. I can use the headphones when I set up sound/playback/S/PDIF however the sound is greatly diminished..and just like the speakers I cannot control them in Xonar Audio Center at all while under S/PDIF. I can control them under sound/playback/speaker however the speakers themselves do not work under this setting. As well I cannot control the speakers via Xonar Audio Center at all...unless im checking PCM which I have to do in order to get the speakers to work at all.
An exp of Xonar Audio Center not recognizing the speakers would be when I do the sound test I receive no audio from either speaker. However upon playing anything normal..music..movies..etc.. the speakers seem to work. However, if the speakers are being used at a diminished quality just like the headphone seems to be when under sound/playback/s/pdif I would really like to get this fixed.Edited by jdlutz89 - 12/1/12 at 7:33pm
