You didn't say what you were using as a source for the signal going to the BFD. If you set your receiver volume to about the highest level you would ever likely use for a movie, and play a 50Hz tone (that you can download and burn to a CD from here), do you still never attain a yellow or red LED on the BFD?
OK, that worked. I have the input set correctly, +3 db and I get some yellow at about the highest volume I would normally use. Thanks!
Now on to my next problem. After about 14 trips to Radio Shack, I think I have everything hooked up correctly. First sign I had problems was setting the input volume. (BTW, it is an Audigy 2 sound card. I have the SPL meter connected to the line in. I have one of the line out directly to the input of the BFD) I get a message that the input volume is set to the max. Don't know what I can do about this, so I move on. When I get to Automatic Measurement, I get this message:
The highest level in the measurement is just -99.3 dBFS
This doesn't seem good and I don't think I am getting anything that I can use. Any ideas? This is rapidly pushing me towards the fridge and a cold beer to lower the frustration level! :blink: TIA
On Audigy 2 selecting the Line In is done by selecting "Analog Mix" in the Record panel of the Basic tab of the Creative Surround Mixer then going to the Source panel and muting all the sources except for Line In. Also in the Advanced Controls (usually accessed by clicking the + symbol for the input) you need to have Record Without Monitoring selected.
Hmmm, now I can not get a loopback signal. I see exactly what you are talking about in the mixer control and have selected analog mix with record without monitoring selected. It does not detect a loopback. I have the line in connected to the line out on the card. I'll have to mess around with this and see what I can get. Thanks.
What U Hear just records what you are playing, it is in effect an internal loopback. Did you make sure Line In is not muted in the Source panel and the other sources are muted? Is the SPL Meter input on REW set to use the same channel you have connected for loopback? (i.e. left or right as appropriate).
Line In is not muted, set to Analog Mix and every other source is muted. As to the channel connected for loopback....you have me for a loss there. I have the line out connected to the line in on the sound card. On the Audigy 2, there are three line outs, not a left and right channel. I have tried them all. Not sure what is going on.
Cards that support multi-channel (e.g. 5.1) typically have a number of stereo jack sockets for each pair of channels, so the 3 line outs on your Audigy 2 are probably L/R, C/sub and SL/SR. Use the L/R connector. If your loopback connection is a stereo jack plug to stereo jack plug lead then that's fine, both channels are connected so doesn't matter which you have selected.
If it works OK using What U Hear then that suggests the output side is working OK and the problem is getting the line in going. There might be some clues in the soundcard debug file (generated via the entry in the Soundcard menu), so worth generating that and sending it to me along with a screen shot of REW when set up with the loopback connected, the signal generator turned on and the SPL meter turned on.
Thanks John. I'll have another stab at it this week or weekend with that help and see how it goes. Thanks!
