LH Labs Geek Out v2+ Discussion Thread

[bhazard]

  I received my GOV2+∞ the other day and have been giving it a bit of a workout. I've run it through 2 complete power cycles and it takes approximately 5 hours to fully charge. Is anyone else experiencing these long charge times ? The 2nd time I used a LH Labs 1G USB A to Micro B cable and a good 2A charger. Generally I can charge a 2800mah battery in 1hr 40mins with that charging set up. 
 
I understood the power light indicator would turn red before shutting down, I never noticed I noticed a red light either time (wasn't waiting for it, but never noticed) and the unit simply powered down. The second time it was connected to a PC workstation using JRiver and when it powered off it locked out the Task Bar in Windows 10 - had to reboot the PC. Seems strange. Otherwise performance on PC's with Win 10 as system audio worked seamlessly (also used Surface Pro 3 with JRiver).
 
My main interest is Android audio - portable HiFi. I'm struggling with this. My Fiio E18 uses a different type of B2B OTG cable which (won't work with GOV2+) once connected, Android recognizes the USB DAC and operates as system level audio device. OTOH, the GOV2+ can only work with certain apps ? Like UAPP & HibyMusic and not as a system level audio device?  That seems lame!
 
I've been able to trick GOV2+ to playback from Google Play/Tune In/YouTube and system sounds from my phone - but something is off with the SQ and it lights up the 4x LED on the GOV2+. 
 
I'm assuming that this has to do with limitations of Android USB Audio standards for hi bit rate files, but why not do both?
 
My android devices include OnePlus One & OnePlus X, both with Sultan's CM13 ROM, and Nexus 9 stock.

Use a micro-usb to micro-usb cable (both ends) and USB Audio Player Pro (or a USB-C to micro-usb cable). Works great on most Android phones with the V2+.

Hmm I was hoping it would work with spotify. Got my first android phone and was disappointed to find that the Infinity was the only dac to not work plugged in as is with Tidal and Spotify. 
 
Lame sauce lol

My Infinity works with Poweramp, Spotify, Jet audio and UAPP.

It does? Which phone are you using? I think it might have to do with phone compatibility. I am using it with a Note 4.

After first V2+. Stopped working. One channel on the balanced jack was silent on 2nd "NEW" V2+

After This experience with LH Labs , I will not back any "starter " projects ever again !
After 9 months since first backing ,I have a working unit.

I tried several different combinations to rule out wire culprits
 
a) Micro Usb to Micro usb - works with the E1K but not V2+ Infinity
b) Micro Usb to Female USB (OTG Cable) -> ZuperDAC (plug and play with spotify)
c) a) Micro Usb to Female USB (OTG Cable)  -> Male USB to Mico USB -> V2+ (didn't worl), E17K work

Yeah having similar problem on a phone running Android 6 - no issues with Android out, but everything is being converted to system audio output so it shows 4x no matter what is being played, can't get Neutron to detect it for direct output. Still sounds fine though AFAICT, guess it might be an issue for people trying play hi-res stuff.

HTC 10. Note 4 did have some niggles as I couldn't get the Infinity to talk to it properly.

Hmm, my phone as well (^5!) .... Maybe it's just Neutron or something in my settings preventing direct output. Will have to try the apps you mentioned.

UAPP is pretty much bullet proof.

My Infinity has arrived and it sounds really good. Some issues when connecting to Galaxy S7, does not always work at the first try and the S7 speaker gives out an interesting horrible crackling noise when connection fails.
 
Pairs nicely with HE-500 and TH-X00 Purplehearts. Only tried SE so far with HE-500. Need to build the balanced adapter.

When using UAPP (USB Audio Player Pro) as app.

Happy on ticking these settings:
-Use USB DAC
-Android Sample Rate:Native
-Bitperfect
-DSD ModeoP
-DSD High quality conversion

I'm afraid it's the phone, my G3 and Z3Compact works fine with Spotify while my M7 doesn't.

Also make sure not to use the OTG cables made for FiiO DAPs since they typically don't work with other gear (only amp/dac I've ever got it working with is the Opus #11 and I've tried quite a few).

What differences are people experiencing in volume levels between the two power settings?

On my HE-560's there's only about a 5% increase in volume on the high setting.

I agree, but my point is it should work as a system level player, ie even playback system sounds from your cell phone like when you touch the screen.
 
I can "trick" the Infiniti to playback system level sounds and apps if I simply pause UAPP or HibyMusic and start some other app. But, as soon as you close the USB Audio App it will kill the playback and nothing will play on Infiniti. When it is "tricked" it displays the 4x LED - which means what - maybe your experience is different ?
 
I'm not sure about SQ when it's tricked - Google Play didn't seem right but Tune In sounded Ok - maybe Spotify is Ok under this scenario.
 
Again, curious to see if anyone else has issues with GOV2+ Infiniti playing back at a system level. My understanding is Android is limited to 48khz (?) so USB Audio Apps are needed to bypass Android to allow higher bit rates to be streamed. Just don't understand why it can't do both... if UAPP is bypassing Android - why can't it handle the system level stuff when the USB audio app is off.
