I've been using Guitar Rig 4 for a year or two, and it's a fairly useful toy for a bedroom guitarist. Currently, I use a Behringer UCG102 USB interface, which has a guitar in and headphone out.

When connected to my computer, it works fine, I get the modified audio via the headphone out. However, if I want to listen to practice materials, media on my laptop for example, and play along, I have to jump through a few more hoops; my current setup is to use a 1/4" lead from the headphone out to my amp, use a 3.5mm cable from the headphone port on the laptop to the same port on my amp, and then plug headphones in my amp. This way I can get both my guitar audio and computer audio at the same time. It's convoluted, but provided I have an amp, it works.

However, I'm away from home at the moment and don't have access to my amplifier, though I have a guitar and USB interface along with GR software. I can't seem to configure the ASIO4ALL drivers in such a fashion that I get the normal laptop output via the USB interface, without cutting off the output from Guitar Rig. Can anyone advise me on a way to have the two working simultaneously?

    Also, yours seem to be a common issue with ASIO4ALL drivers. It might be the case that in some system combinations (or maybe always?) you just can't hear more than one sound source. See mtippach.proboards.com/thread/786/… and forum.cockos.com/showthread.php?t=123165 and – Lyd Jun 23 '14 at 23:09
  • I've had this multiclient ASIO problem with Lexicon Alpha. The best solution I found after tons of research is using ASIO Link Pro, and still there was a small latency that was annoying. I have decided to buy a Steinberg UR22 MKII. I can confirm it works flawlessly, with no latency whatsoever, and without any special configuration. Their ASIO driver just works perfectly. I am playing Spotify / YouTube while playing my MIDI inside Ableton. My setup is Windows 10 + Ableton Live 9.5. – amiregelz Dec 28 '17 at 17:25

I think I know where is the issue. My Windows-fu is rusty, but here is what I found.

Solution, in short

Get ASIO multi-client from here or here (they are different, you might want to try both). After installation you should be able to use your interface with more than one program.

What is happening?

Seems that ASIO in general (including ASIO4ALL) can't handle more than one program using one same output.

Support for using ASIO with multiple programs at once. Previously, if you were using an ASIO driver (so that you have low latency), you could only use ASIO with one program at a time. Now you can use multiple programs at once with ASIO - for example RealBand and Band-in-a-Box at the same time.

Steinberg solved this by creating an ASIO multi-client server that you need to download and install. Seems that this is exactly what you need, and seems to work with all ASIO capable interfaces.

More info: http://www.pgmusic.com/forums/ubbthreads.php?ubb=showflat&Number=237170

There are other ASIO multi-client drivers you can try, like this one: http://vidance.com/asiomulti/asiomulti.html

From the above, we discover that:

ASIO (Audio Streaming Input Output) is a technology of Steinberg. It allows for low latencies and pretty much every state-of-the-art audio device is nowadays delivered with an ASIO driver (on Windows, at least). However, the basic idea behind ASIO is that professional audio applications entirely take ownership of the ASIO device. Only very few ASIO drivers support true multiple application access. This effectively means that you can not use 2 or more applications using the same ASIO device at the same time.

In other words, you'll need Steinberg's or Vidance's ASIO multi-client driver to route more than one program to the same audio interface.

Another alternative is to use JACK

I found some people were using JACK to solve this issue. It's an internal routing system for audio and MIDI. If it's anything like Soundflower, I believe they might be routing everything to JACK, and then routing JACK to the audio interface, using JACK like a mixer.

Edit: I've recently tried to use the Steinberg ASIO multi-client in Windows 10, and couldn't get it to work. The driver is really old and not officially supported, so it might be obsolete now (it probably works in other versions of Windows, but I can't test that atm).

What I found is that many audio interface manufacturers have a multi client built in in their ASIO drivers, so look for those specific interfaces if you want an easy solution.

Still no idea on how to solve this for ASIO4ALL though, other than the multi clients mentioned that might or might not work in different versions of Windows.

    I remember to have tried Vidance's and Steinberg's ASIO multi-client driver in the past, but did not achieve to do this (have you been successful with this @JCPedroza?) : Run DAW (for example Ableton) with ASIO4ALL and have Firefox playing a Youtube video at the same time. Is this possible with one of these ASIO multiclient driver ? [Here it is ASIO + WDM at the same time rather than ASIO + ASIO at the same time, because Firefox doesn't use ASIO] – Basj Feb 14 '15 at 20:56

I found this here http://odeus-audio.com.au/Odeus/AsioLink and it lets you listen to windows audio as well and send audio over the network.

The price $39.95 AUD on Nov 10, 2016 so please ignore the price information in the below comment by mateen-ulhaq.

    @mruellan This is the best solution I've found after struggling with the same problem for two weeks. It's unfortunate it's impossible to purchase it legally. In any case, Team AiR crcked AsioLink and it works perfectly. – amiregelz Dec 11 '17 at 21:55
  • Alreay tried, But windows defender detected a virus. I have found a workaround to my pb. I bought Reaper and now all my vst works like a charm (with midi aftertouch for the drum). I needn't standalone versions anymore. – mruellan Dec 12 '17 at 11:21
  • @Rob After having tried to solve this problem since more than 10 years, and tested all possible software/driver, AsioLinkPro was indeed the only working solution, as of today. – Basj Oct 5 '18 at 11:46

The answer depends a good deal on your operating system and precise setup, but you should be able to do this purely via software.

  • Try routing Guitar Rig's sounds into a DAW, and then listen to your DAW's output via your laptop speakers/headphone jack. This way you will have a software mixer, and be able to hear your effects laden sounds.

  • Try switching your core audio drivers over to the guitar rig, so that all audio is sent through it.

For what you are trying to do, you might have a lot more fun if you switch to a more fully featured sound card, such as those provided by M-Audio, or presonus. They make doing this kind of thing very easy.


You can get literally thouands of guitar effects for free via the VST plugin system.

  • "The answer depends a good deal on your operating system and precise setup" He mentioned ASIO4ALL, so I'm assuming he is running Windows. – Lyd Jun 23 '14 at 22:55
  • "Try switching your core audio drivers over to the guitar rig, so that all audio is sent through it." Core audio is for Mac. The asker is running ASIO4ALL. – Lyd Jun 23 '14 at 22:59

There's a recorder and a player in guitar rig I use it all the time. You drag a track and drop it over the player and you can play it and slow it down and change the pitch. Its a pretty useful tool helps with practicing. You can't play another media application on your PC if you have asio as in the first answer


MOTU and RME are the only interfaces I know so far that use multi-client drivers. I have engaged some manufacturers and their support people don't even know what they are. I didn't either until I bought a non-MOTU interface (TASCAM US20x20 which I actually liked). I have tried the workaround drivers to no avail. I guess I'll stick with MOTU. They said they have always used multi-client drivers. It's critical for me to switch back and forth between audio apps without closing them down. Seems like a no-brainer.

  • That's right, MOTU drivers are excellent for this! Multi-client is rare... Some Tascam do have multi-client too (US122L sure, and US1800 maybe, too, IIRC) – Basj Oct 4 '18 at 23:05

Try using a good external audio board for the daw audio input (like: computer audio out through a splitter(to input A of the splitter) in the external audio board with the guitar rig output(to input B of the splitter)so you can also record the audio of the backing track and your guitar together (figure out what you may do with two good external audio boards paired together... for example: computer out to external audio board 1 in and guitar rig out(if hardware) or in(if software) to/with (depends) external audio board 2 in in a way to (also) record the audio with your favourite daw of your guitar(effected) and the computer on two separated tracks


I've spent years on this problem, trying every new solution (different ASIO drivers, virtual cable software, etc.) when I found them.

In the article Low latency audio on a Windows PC with the built-in soundcard I give the detail of all working and non-working solutions.

TL;DR: these don't work directly for this purpose: Asio2KS, Vidance AsioMulti, VirtualAudioCable, etc. The best solution available is the one suggested by Rob's answer.


There is no Issue, just set the speakers to the same out put as the interface is on. if you are using asio of 44.1k and interface is at 48.0k you will only hear one, so make sure all sound is at the same 44.1k and everything should work


I also bought a Beheringer Guitar Link as an input device for my laptop and am frustrated with it. The ONLY solution that I have found that works perfectly is my Line 6 Guitar Port, which I have connected to my desktop. The problem is that the AISO driver takes over and de-activates your sound card drivers. That means that only AISO programs work and not things like Firefox or Chrome. Using a proxy AISO program allows you to use multiple ASIO programs but not programs that use your sound card drivers simultaneously. Guitar Port works differently. It becomes your sound card and allows all programs to access it equally. I use it all of the time with Youtube, my audio collection, etc. I guess I'll be buying a second Guitar Port.

  • old post, but this is false information: "sound card drivers" are not deactivated. If you were to route the output through the behringer headphones to external speakers, you would be able to use the laptop speaker/headphone out to listen to audio simultaneously. you would need speakers for each. – Yorik Nov 10 '16 at 15:53

I would recommend VB-Audio's ASIO Bridge, the only solution that has worked for me so far. It creates a virtual playback device named "Hi-Fi Cable Input" that will "capture" audio from your ASIO driver (in your case ASIO4ALL).

It's free and easy to configure, you just have to launch the ASIO Bridge and select the correct ASIO driver, and it automagically works!

  • "VBAudio's ASIO Bridge" is a cool tool, but it does not work in this case: Software #1 in ASIO mode => ASIO4ALL // Software #2 in WDM => ASIO Bridge => ASIO4ALL. The latter does not work because ASIO4ALL is already in use by Software #1. ASIO4ALL is not multi-client. – Basj Oct 5 '18 at 11:44
