I'm willing to let you remote access to the "problem computer" so you can take a look at the problem and hopefully fix it...

See whether anydesk works

[VadosG]

Yes, it works.

no clue now.

Nothing special and still no clue.

Your pc sound plays out by "Realtek Digital Output (Realtek High Definition Audio)" or "Динамики (Realtek High Definition Audio)" ?

[VadosG]

I've tried both already - no sound. But mostly Realtek Digital Output, sets as default.

[VadosG]

I have encountered this problem on at least 1 PC with Windows 10 and 2 PC with Windows 7 (both x64)

[VadosG]

I really need help with this issue. I can't work without sound :(

[VadosG]

Maybe some special exe for tests/logging? I'm ready to run anything to find the root of the problem.

https://github.com/21pages/test/releases/download/test/cpal_record_wav.exe

This program record wave of your default audio device, run it via terminal, it will print log. This is mine.

Default input config: SupportedStreamConfig { channels: 2, sample_rate: SampleRate(48000), buffer_size: Range { min: 0, max: 4294967295 }, sample_format: F32 }
Begin recording...

You can change your default audio device with https://github.com/xenolightning/AudioSwitcher_v1/releases/download/1.8.0.142/AudioSwitcher.exe

Input device: Динамики (Realtek High Definition Audio)

Recording ./recorded.wav complete!

I have achieved audio availability. If you make the default device analog audio (not digital!), turn on the stereo mixer in the recording devices, and in the RustDesk settings select audio capture from the stereo mixer - the sound works. Tested on 1 PC with Windows 10 and 1 PC with Windows 7. Don't rush to close the issue yet, I need to test on a few more PCs...

Ou! Thanks! It's realy work!

In general, it is very hard to say, but it seems that Realtek audio cards are affected. On one of the PCs, the sound was captured normally from Nvidia HDMI with the Realtek stereo mixer turned off (simply put, without any settings). I already thought it was because of the cyrillic name of the audio output (Динамики), whereas Nvidia has a completely latin name. I renamed Динамики to Headphones - nothing happened. It's hard to say, but the problem is clearly there and difficult to understand.

Note: AudioSwitcher.exe did not help me, I did it without it.

How to solve? I also am w10 remote w7 no other software has a voice

[kokpk]

我能听到麦克风录到的声音，但是听不到被控电脑本身播放的声音。

I'm remoting into a HyperV VM with VBCable virtual sound device. Audio from TeamViewer and AnyDesk can be heard, but nothing from RustDesk.

Using cpal_record, I see this written out to the console:

Input device: CABLE Input (VB-Audio Virtual Cable) Default input config: SupportedStreamConfig { channels: 2, sample_rate: SampleRate(44100), buffer_size: Range { min: 0, max: 4294967295 }, sample_format: F32 } Begin recording... new_input 1 new_input 2 run_input process_commands_and_await_signal result: false run_input process_commands_and_await_signal result: false run_input process_commands_and_await_signal result: false Recording ./recorded.wav complete!

Any help to get audio working with the VBCable drivers, please?

@fufesou take note of above, let us check after asio.
