MC suddenly stopped working with DAC
« on: April 27, 2014, 07:55:03 pm »

Hello, my PC has dual use through the projector in the media room and connected to my external DAC for headphone use (Renaissance Labs Herus)

After spending a few days in the media room, I have just connected it back to the DAC, and now it won't work anymore. I have different zones set up for this purpose. No settings were initially changed.
It will play for one second, then stop with the error message to try 44.1 2-channel format. I tried changing different output settings such real-time DSD conversion, no DSD conversion, manually setting the output format to 44.1, turning the Output Format off completely in DSP studio. The results are all the same, it plays for one sec, then stops. The one sec that is plays is fine.

The DAC is working just fine with other applications.

I just tried reinstalling the same version, and for whatever reason, that fixed the problem......

Well, though no one has responded thus far, I would like someone to provide some insight on using the Open Live feature, which I plan to use quite a bit to listen to di.fm and Spotify.

I keep having mixed results with this. Sometimes it works, sometimes it doesn't with no apparent reason why. Sometimes I have to keep changing the default Windows audio output back n forth several times to get it to finally start working. Sometimes I have to completely close Spotify or the browser running di.fm and restart that to get it to work. Sometimes I have to completely close JRiver and restart. Sometimes I just give it up, listen to my own stuff through JRiver, and try again in a few hours, and then it just magically works again.

It is a great yet frustrating feature, but I assume I am lacking some knowledge of how this is supposed to work.

I have no real insight other than to say I feel your pain.  If it is not working, I typically just have to close Media Server and restart it to get it working.  The bigger issue is that I've played with buffering and live playback latency hundreds of times to get rid of clicks and pops.  I'll finally have it working perfectly, only to come back an hour later to have it stuttering again.  I have yet to find a "set it and forget it" option/setting.

I agree, it is a great yet frustrating feature.  For now, I have just given up on it.

I don't usually have any problems with Wasapi Loopback (I assume that's what you mean by Open Live, and not ASIO line in), but I can offer a few suggestions assuming you mean WASAPI loopback:

1) When it says "opening" but nothing comes that usually means that either it's waiting for input and there isn't any where it expects it, or that something else is playing to the same output that JRiver is trying to output to.  This could happen if you, for example, have the same device set as the system default as you have set as JRiver's output.  If that's the case, that's not optimal and won't work correctly; you need to set the windows default audio output device to a different device than JRiver is using for output.

2) If you have a different device set as the default, the problems you describe could easily result from something (web browser, flash player, etc.) taking exclusive control of that device.  That can sometimes interfere with JRiver's loopback grabbing the audio.  If you open your default device's properties in windows, is "allow applications to take exclusive control of this device" checked?  Try unchecking it, that can produce much better results.
 
3) Does it matter what browser you use?  The flash plugin in firefox can be a little "grabby" and can sometimes interfere with loopback.  It usually works fine for me, but if you're a firefox user, try using a different browser and see if it helps (just as a troubleshooting step).

4) Try setting up a separate zone for loopback playback using zoneswitch rules to route the audio.  That way if you need to do special configuration for loopback, you can, and I've found it works more smoothly when switching what's playing in JRiver.

I have no real insight other than to say I feel your pain.  If it is not working, I typically just have to close Media Server and restart it to get it working.  The bigger issue is that I've played with buffering and live playback latency hundreds of times to get rid of clicks and pops.  I'll finally have it working perfectly, only to come back an hour later to have it stuttering again.  I have yet to find a "set it and forget it" option/setting.

I agree, it is a great yet frustrating feature.  For now, I have just given up on it. 

Have you tried testing your overall system latency with a tool like DPClatency checker?  If your system has serious periodic latency spikes it can really nerf loopback in an intermittent way that's hard to troubleshoot and often is a driver or process issue that has nothing to do with JRiver. 

For example, I used to have very rare issues with pops and clicks with normal playback, but they became frequent and enormous when I started using loopback.  In that case the problem wasn't JRiver or any combo of buffer settings, it was the stock Asus drivers for my soundcard (an Asus DX).  Once I replaced the drivers, all problems went away.

Thanks for the feedback.

Yes, I am using WASAPI.

Yes, I know the outputs need to be different.
Your explanations would seem to apply if this wasn't so intermittent and/or I was listening to all kinds of different things.

I listen to Spotify and di.fm only through the Live function and so I think 2) does not apply here, but I will change that setting just to be safe.

I don't use Firefox.

I would like to learn more about the zoneswitch rules you mentioned, so I will look into that.

It seems like the software has trouble going between Live and DSD real-time conversion.  Once I get either one to finally work, it works until I try to switch it again, then sometimes it works fine and sometimes it doesn't.

Thanks for the tip.  I hadn't tried DPClatency checker, so I just downloaded it.  Latency does fluctuate between ~150-250µs, but no huge spikes.  With Live playback latency set to 100ms for my Loopback zone, it should be fine.  Of course, I wasn't getting any clicks or pops this morning either.  I'll play with it again later to see if I can catch it when it's stuttering.
