Title: Help from Audiophiles
Post by: maid on March 07, 2012, 07:48:47 pm
It seems every time hubby wants to listen to music there is something wrong with the sound
Music is flat nothing is coming out of the back speakers.
We have tried rebooting the computer but nothing helps, but switch it back on the next day go straight to music and it sounds great
Could this be something in windows 7??


Using ROHQ
Output Wasapi digital audio
DSP Source number of channels ( although when I tried two channel this morning it was still using all speakers??)

There shouldn't be a difference between rebooting and turning off and starting the next day. Could your AVR be acting up/getting too hot?

If you want the back speakers engaged and you are listening to stereo audio, you will need to enable upmixing in the DSP.

Do I put it on source 5.1 or stereo?? to play on all speakers.

Most source audio is 2-channel stereo. So, if you put it on 'source', you will only get the left and right (front) speakers working. Many who consider themselves audiophiles prefer this. I think you'll want 5.1 if you want the back speakers active too.

If i put it on 5.1 Wasapi says there is a problem with playback

What are you feeding the digital signal into? If it is an AV proccessor then this will dictate how this is handled. You could easely have 2 channel enabled on MC17 and the AV amp send out as say dolby prologic or DTS

it seems to work set on Stereo, I think that it may have been my fault as I set it on source thinking that meant how many speakers we have.

MC has become a little difficult for the average joe blow too many settings for audio and video.

No, the only way it's working (if by working you mean all speakers are active) is if your receiver is upmixing the sound for you, using some variant of Dolby Pro Logic for example. If you want consistent results, you really should set JRSS to output to 5.1.
The setting you're adjusting is most simply (and simplistically) described as "How many speakers do you want the sound to come out of?". This assumes your receiver will not mess with the audio and upmix to more speakers.

1) By selecting stereo, that means two.
2) By selecting "source" that means however many channels the original audio file had, which in most cases is also two (stereo).
3) By selecting 5.1 you ensure that all audio goes to your AVR as 5.1 at all times.

Scenarios 1 and 2 may be overridden by the settings of your receiver (AVR) as mentioned in my first sentence. Your ideal solutions are:
Either-
(2) but with a Dolby ProLogic II, DTS-NEO, or other upmixing mode activated in your AVR.
OR-
(3)

Choosing option (1) might cause all kinds of trouble in the future, especially if you don't bitstream movie audio, but rather decode in MC.

As I said I tried putting it on 5.1 Wasapi but there is a playback problem and it resets to Stereo.

Why does Wasapi not work on 5.1? What else can I try??

Try wasapi event style? Change the buffer settings too; I think matt recommends 100 ms or less.

How is the computers audio attached to the AV receiver? If it's a single cable sending a digital signal then simply setting MC17 to 5.1 and JRSS won't give you sound in all the speakers unless you bit stream a dolby digital signal. If this is the case, in DSP Studio check the box "Output surround sound as Dolby Digital" This will encode the 5.1 channels MC creates to a format that the AV receiver can decode into 5.1 speakers.

Not quite true if it's an HDMI cable.

You also have to have the Bitdepth set to 24-bits if using an HDMI cable. Most receivers only accept 24-bit multi-channel PCM.

Good point but I didn't see anywhere in the thread that HDMI was mentioned and I looked up the specs on the AV receiver in Maid's signature and the Kenwood KRF-V5100D doesn't have HDMI.

I seemed to recall she didn't have HDMI, but was too lazy to go search her previous threads to see if she'd upgraded. But it was there in the smallprint! :)

We use a Spdif cable. I think it is now fixed as we have ticked the 5.1 Dolby. Thanks

If I use Bitsteaming for Video, what should I set my audio on??

I don't think you need to change anything in your audio settings. Just select S/PDIF for the bitstreaming in the video playback options.

SPDIF would do the trick.

Or you can leave it the way it is. If all you have selected in the DSP menu is 5.1 channels, and and the Dolby Digital box check the end result is the same.

UNLESS, you're aiming for DTS. In that case bitstreaming => S/PDIF is your choice.

Bitstreaming will bypass the settings you have in the DSP Studio, and you're receiver does all the work.

If I use Bitsteaming for Video, what should I set my audio on??

Is a bit vague, so I tried to cover some likely possibilities for "audio".

Good Luck

I have made zone one for hubbies music using 5.1 as he likes the DSP studio over our amp.

I have made zone two bitstream for movies and I dont need DSP.

Sounds like a win/win.

hope so as long as the settings dont vanish again
