    Why even bother posting then? Sounds like you just want an excuse to rag on the Chinese.

    Good luck with support. I'm still trying to get LH Labs to ship a GO2A that I bought on February 18th. They are still selling them. I don't know if they are still shipping them.

    Maybe there's a communication gap here. How can you sell something that doesn't work?

    sounds like you love to burn money for no reason. I'm in Germany too, just send me the money instead of burning it

    But seriously, why not send a simple email to support? I'm sure they will take care of you. Unless you messed up and dropped water in it and thats why it doesnt work anymore.

    @GoodEnoughGear he says he will sell it "as is". In germany (and holland in my experience) people do that a lot. Usually for stuff that cant be fixed or is too expensive to fix but sometimes you get lucky when someone is selling as is because they're just too lazy to do it themselves

    As of today, my GO2A will NOT WORK in my laptop. I've turned off driver verification, I've reset, I've run troubleshooting, I've done everything. I now have something that I've spent almost 400 dollars on that is useless. The PC won't even recognize the unit. WHEN IS LH GOING TO SUBMIT THEIR DRIVERS TO MICROSOFT??!?! I'm going to submit a ticket to LH Labs or I need someone from LH Labs to on here to help me with this.

    Edit: My GO 1000 does not work either. When I get home I'm going to try my 450 and then I'm going to try my Dragonfly Black. This has to be something software related directly to LH Labs.

    What happened to your unit? What happens when you try to use it?

    Yep, next test would be dragonfly - if that doesn't work either, then it's your machine most likely. Is there anything in the event log that sheds some light?

    UAPP and GO2A (and presumably the other GO units) volume control observations

    This post was prompted by me almost blowing my eardrums with the GO2ASE and Android because of some idiosyncrasies with the Geek hardware volume control.

    I'm not sure what the default is, but I had UAPP configured to show the hardware volume control slider at the top like so:

    Screenshot_2017-03-30-10-32-46.png

    As you can see, it defaulted to 100% as the GO units are wont to do. Aaaaargh, I rip the Andros out of my ears and thank heavens that I'm only on 100mw.

    So, I adjust the volume on the slider, press play, and all is good. Then the track changes, and the slider reverts to 100%. A millisecond of panic, and then I realize the volume hasn't changed with the slider. WTF????

    So I do some messing around in Settings to no avail and then notice the Hardware Volume control panel (press... on the top right and select "Hardware Volume")

    Screenshot_2017-03-30-10-33-38.png

    You have the familiar Geek volume Master slider and individual channel sliders. Here's where the behavior is weird: The Master slider works, but the channel sliders don't do diddly squat. Here's what makes it frustrating:

    Apparently the hardware slider on the main screen can either lock to the main slider (master) on the left, or the channel sliders on the right of the Hardware Volume control panel. If it is locked to the Master slider, volume control works fine on the main screen. If you are locked to the channel sliders, the volume control is effectively useless - I can discern no volume change at all. Moreover, on each track change it reverts back to 100% if it's locked to the Channel sliders. I have also seen the case where it is locked to the Master slider (so it works) but on track change reverts to the Channel sliders and shows 100% even though the Master slider is at the level you selected (say 50%). So the volume is 'normal', but on the main screen it shows 100%. It appears that in general whatever slider you last touched is the one that reflects on the Main screen, but that it can 'flip' from Master to Channel on track change and maybe in other cases.

    That's just too f'ing wonky for me. Anyone who understands this behavior better please chime in, but I have elected to 'solve' the problem this way:

    I have set the Main screen slider to reflect Software Volume Control so I have consistent behavior and none of this Master/Channel confusion crap (note if you select the bit-perfect option this will be grayed out). At least the volume control works consistently if it is enabled in this configuration. In my case I use the Hardware Volume control panel Master slider for volume control and set the bit-perfect option.

    This may save you an eardrum or two.

    Tested it. The Dragonfly works flawlessly. Other USB devices work flawlessly. I uninstalled the latest LH Labs 3.26 Audio Driver, and installed the earlier 2.29 (using Windows 10). The DACs now work with that software. What's really weird is the 3.26 version still works on my desktop (Windows 10).

    I'd be curious if Device Manager shows the Geeks at all (either in an error or disabled state) or if they just don't show up at all under 3.26 - though I understand if you don't want to mess with something that's now working. Anything in the Event Log?

    Bit of a silly question, as there is probably a formula to calculate this that I am unaware of. Using the GO2A as a DAC to my amp, how would I calculate the 100mw-1000mw low and high gain settings, to volts? 100mw=?V, 1000mw=?V? I know some amps have max input voltages, so I'm just wondering if I should use high or low gain. This is using the balanced output btw. If I haven't provided enough info let me know, any help would be appreciated. Thanks guys!

    Also, my cable should be here later today! TRRS to 4pin XLR adapter for use with headphones direct, and an all male 4pin XLR to dual 3pin XLR adapter for use with my amp. Yay.

    I'll see if I can check on that later.

    Thank you!!!


    However, its time for another dumb question. I've just received the cable, and plugged it into my amps XLR Inputs. With the amp on, and headphones plugged in Im getting a buzzing noise/hum. The Cable is unplugged at the other end, however, if I plug it in (with my computers charger plugged in) the buzzing/hum gets worse. The noise lessens if I touch the amp, but is still present. Is this a grounding issue? Im an electrical engineering luddite, so I'm a bit puzzled. I'll post this in the technical help thread if I can find it as well. Thanks for any help in advance, and apologies for the dumb questions.

    I have searched, before I posted, and came up with this.

    "Yes you can do that without a problem, but you may also need a TRS->RCA as well to ground it. I and others have gotten noise using a TRRS->XLR cable without also having the SE plugged in."

    But as the noise is happening without the source end of the cable plugged in, I'm pretty sure that isn't the right fix for my situation. However, as it isn't, I probably shouldn't have posted my problem in this thread. Apologies.

    OK, sorry, no disrespect intended, just checking you were aware of the feature...

    Unplugged cables can also cause hum by acting as an antenna, not technically a grounding issue but the effect is the same. If you can reduce the hum when everything is plugged in by touching the amp then I agree that that is pretty certain to be a grounding issue. So I would say it seems reasonable to try out a TRS->RCA in parallel to see if it helps...
