Sound is not recording by OBS

[SAARussian]

How I can record sound from the game with OBS through rs_asio?

If your device exposes a loopback interface, you can use that.

Alternatively, you could try to use ASIO only for the input, and use WASAPI for output by setting Driver= on the output, and setting EnableWasapi=1. This way if your default audio output device has a loopback feature (for example, Stereo Mix on realtek onboard audio) you can record using that.

If you want to output through your interface and also record, you'll have to find a way to split the audio into your headphones/speakers and also into your computer's normal soundcard line-in or something like that, as with ASIO the device is completely owned by the user application (which is what allows low latency).

Recording with RS_ASIO itself is not a feature I will add.

can I use wasapi + asio4all with my soundcard and will it do a lot of latency?

[mdias]

You should be able to use WASAPI + Asio4all, yes.

It's not possible for me to tell you if latency will improve or not. But there's actually a chance it can improve.

[SAARussian]

how should I named that driver in rs_asio?

[SAARussian]

Driver=BEHRINGER USB AUDIO don't work

[mdias]

If you look at my first reply it says there what you have to do to enable WASAPI for output while using ASIO for input.
If that doesn't work, please post the log file.

Here I just decided to try with a different driver to run the game, or do I need to open a new issue?

[SAARussian]

Yeah, no sound from input

Your output "Driver" line is not empty. As I said in my first reply, if you want to output through WASAPI to be able to record, you need that to be empty to make sure the game will select the wasapi device.

As for the input, it would be weird if you had it working before, but not now. But if you can try disabling all your recording devices in the windows audio device manager, except for the one you want to use.

OK right know I have 11.1 ms latency with this strange asio driver versus asio4all 256 samples / 48000 sample rate x 2 kernel buffers x 2 (input + output) x 1000 = 27 ms latency


But what about default rocksmith driver with nocable patch? 160 MaxOutputBufferSize (samples) / 48000 x 2 LatencyBuffer x 2 (input + output) x 1000 = 13.3 ms latency?

Are my calculations correct?

Anyway with your feature I can use second HiZ input channel (thank you very much for this, God bless you xD), but how you think can I do it with nocable patch + voicemeeter without RS_ASIO?

[mdias]

Your calculations are mostly correct, but it only accounts for the latency introduced by the buffer size while in reality there is also protocol and bus latency involved. For example, sending 1 byte through USB has both USB protocol overhead and actual hardware BUS overhead which is hard to measure accurately. However I would say a good rule of thumb is to just account for at least 3ms latency just for USB itself, so whatever result you achieve, you can "safely" just add at least 3ms on top of it (if it's a USB device).

Now, depending on which device you're using for the native Rocksmith "driver" (which is WASAPI) latency could be better or worse; unfortunately there's no easy way for me to measure this...

Regarding Voicemeeter, I have tried it in the past but had horrible results (bad distortion and very bad latency) but I've seen other people say it works good for them, so I guess your success may vary depending on hardware.

There are other tricks you could try if ASIO doesn't work the best for you, like having your guitar interface set in passthrough/monitor mode, and just route it's output to your onboard card line-in, and use that with NoCable patch. I personally never tried it, but it seems like it could work.

[SAARussian]

You can add BEHRINGER U-PHORIA UM2 as 16-bit audio interfaces reported to work well

[SAARussian]

Perhaps whom any use to anyone. I don't know if it's all set up correctly, but it works, maybe a way to further reduce latency.

[SAARussian]

It is possible that the rocksmith buffer.ini is added to the asio buffer and the delay only increases. Than without rs_asio.

[mdias]

It's possible that the buffers are added, increasing the delay, yes. However, this will be the case also for normal non-asio drivers.

Is this driver official?
