Hx Stomp audio interface output only from headphones, main output no sound

[dishi99]

Hi guys,

Hope all is well,
been trying to connect the hx stomp to my macbook air m1 as an interface to hear audio like youtube through my studio monitors
i installed the drivers and updated to last version, set my hx stomp as the device for output on the audio midi interface on the mac.
i can only get sound to go out from my headphones jack but no sound comes out from the main outputs, can anyone point me on how to sort it out? 
any help about this would be greatly appreciated
Thanks

Hi,

 

See page 56 - Ins/Outs, plus page 61 USB Audio.

Hope this helps/makes sense.

thanks guys appreciate your help 
i tried changing all the ins/outs settings , it didn't effect anything 
i also looked at the manual on page 61 and it seems i am connecting the hxstomp correctly throuhg the main outputs and even with a blank preste i can't hear nothing unless it's through the headphones jack

 

i noticed i have this error on the system information - disabled software section 
 

VCN535JA6Y - com.line6.driver.helix:

 

  Version: 1.5.0

  Reason: No User Consent

  Date Disabled: Unknown

maybe this could be the issue? the hx stomp does show up on the audio midi settings so i'm not sure it 

would appreciate any help to solve this thing, i just wanna be able to hear youtube / spotify etc 
any tip would be appreciated

thanks

Hi,

 

I don’t know if this is relevant but did you read this:-

 

I have to say that I am running an older iMac Retina 5k on OS Catalina with Logic Pro X without any issues.

 

At various times over the past 10 years I have also used my Helix floor via USB with GarageBand, Reaper, Ableton, ProTools Lite, among other stuff, and it never misses a beat. If I want to, I can use it to jam along to backing tracks from Music (iTunes), YouTube, or whatever. All this is done in the Audio/MIDI settings, or Logic, etc. - I have even had it working configured with 2 other audio interfaces as an aggregate device, adding extra channels.

 

NOTE: You may want to check your monitor system. In my case, I have my Kali IN-8 v2 monitors hooked up to the XLR sockets on the rear of my Helix. You didn’t make any mention of your studio setup, other than headphones.
 

IIRC, on a Mac your HX device should be a simple plug and play unit, and the driver is only required to use sample rates other than the Line 6 default of 48kHz.

Hope this helps/makes sense.

hi there aprecciate your feedback

 

my monitors are hooked witih trs on the main outputs from the hx stomp to xlr on my monitors input, i have genelc 8040 active monitors, these cables worked just fine with an rme fireface 800 and a focusrite scarlet , i managed to sort out the driver issue with support and now i can also change sample rate and lower and increase volume on the volume settings on the mac but still no sound comes out the main outputs 

 

i agree this should be a plug and play thing, i have no idea why i can't figure it out yet, a setup like this should be super simple  

i tried making an aggregate device on the audio midi setup but i have no idea what to do with it, anyhow still no sound, if you have any ideas please let me know
Any tip would be apprecaited 

Thanks

You don’t mention having checked the Global Settings on your HX stomp as indicated in my earlier reply. Did you do that?

Hi,

 

Well, this is weird - if you have used the Global In/Outs of your HXS, available on page 3, then the only options are:-

 

1. Phones Monitor - Determines which signal(s) are heard from the Phones output.
   Normally you would set this to “Main L/R.”
2. Volume Control - Determines whether the top panel VOLUME knob controls both the 1/4" main output
   and headphone output (“Main+HP”) or just the headphone output (“Phones”).
   When set to “Phones” the 1/4" main outputs remain at unity gain.

If your Volume knob is configured to use the phones, then the outputs to your Genlec monitors should be at unity?

 

 

EDIT: You didn't mention if this issue of just hearing audio via the phone socket, only happens on playback over USB.
Does the sound from your HX Stomp play through the monitors if you simply have a guitar on the input

 

If this is not the case, then your best bet is to raise a ticket with Customer Support.

 

Hope this helps/makes sense.
