Update, I have found the root cause for this,
will need to turn off XIAOMI MIUI optimization in the phone setting developer option and restart,
it works well after this.
Thanks for the suggestion.

rom1v · 2023-03-29T08:43:14Z

will need to turn off XIAOMI MIUI optimization in the phone setting developer option and restart,

That may not be the cause for this:

ERROR: Could not open audio device: WASAPI can't find requested audio endpoint: Element not found.

(which is a client error)

SvlarSvlar · 2023-03-29T08:54:43Z

Opss, you are correct,
it works for a while then stopped.

i have tried
using scrcpy-win32-v2.0-18-gd7841664f
set SDL_AUDIODRIVER=directsound
run with scrcpy --audio-output-buffer=10

but now i got another error message
Could not open audio device: DirectSoundCreate8: No audio device found (0x88780078)

rom1v · 2023-03-29T08:57:17Z

You could try with yet another driver: https://wiki.libsdl.org/SDL2/FAQUsingSDL#win32_1

The WASAPI issue will be fixed in the future version of SDL (which will be included in a future version of scrcpy).

moe7863 · 2023-04-13T09:19:26Z

I have experienced the same this morning against the latest release of [scrcpy v2.0].

OS: Windows 10 Pro - 21H2
Scrcpy version: v2.0
Installation method: Windows release
Device model: Samsung S23 Plus
Android version: 13

Describe the bug
Scrcpy opens for a fraction of a second and crashes presenting the error below. As a result, scrcpy is not usable. I have observed the same results using non-console mode

Error output:
ERROR: Could not open audio device: WASAPI can't find requested audio endpoint: Element not found.
ERROR: Demuxer error

Thanks team

rom1v · 2023-04-13T09:38:26Z

Then read #3856 (comment)

Sorted. Thank you :)

leo3487 · 2023-08-01T10:31:02Z

I have same problem at my office pc (Windows 10 pro 32 bits under domain)
After some secs exit with error

could not open audio device: wasapi can't find requested audio endpoint: no se ha encontrado el elemento. error: demuxer error

At home pc is all ok
Office pc has no audio device installed (and seem disabled at bios and cant change it)

Phone is Samsung A03

rom1v · 2023-08-01T10:44:10Z

could not open audio device: wasapi can't find requested audio endpoint: no se ha encontrado el elemento. error: demuxer error

Which scrcpy version? Try the latest, currently v2.1.1 (which includes the latest SDL)

leo3487 · 2023-08-01T10:52:31Z

I guess use same. Downloaded at office pc the 32 bit version less than 1 hour ago, from its github page
https://github.com/Genymobile/scrcpy/releases/download/v2.1.1/scrcpy-win32-v2.1.1.zip

rom1v · 2023-08-01T12:09:41Z

Does it work if you use directsound instead of wasapi? #3856 (comment)

leo3487 · 2023-08-01T12:19:02Z

with
set SDL_AUDIODRIVER=directsound
starting scrcpy from CMD close within less than 1 sec
starting from windows explorer, still same error, after some secs

rom1v · 2023-08-01T12:20:02Z

starting scrcpy from CMD close within less than 1 sec

What is the console output?

rom1v · 2023-08-01T12:26:13Z

And with set SDL_AUDIODRIVER=directsound just before scrcpy? (you should not get any WASAPI error message)

leo3487 · 2023-08-01T12:35:57Z

As error say, it try to find audio device, but as I said at my first post, it is not installed at this pc and seem disabled at bios
There is a way yo start scrcpy without audio?

rom1v · 2023-08-01T12:43:02Z

There is a way yo start scrcpy without audio?

Of course: scrcpy --no-audio.

https://github.com/Genymobile/scrcpy/blob/master/doc/audio.md#no-audio

leo3487 · 2023-08-01T12:45:11Z

Ok. As I suposed, this was the problem
scrcpy tried to find audio but this pc has no audio

Starting without audio now work ok
For next version would be nice of scrcpy automatically detect if no audio device so take correct action to no fail

rom1v · 2023-08-01T12:59:34Z

For next version would be nice of scrcpy automatically detect if no audio device so take correct action to no fail

There is a mechanism to disable audio if it could not be captured on the device (for all devices < Android 11 or with Android 11 when the screen is locked on start). But if audio playback fails on the computer, this is a fatal error (otherwise, audio would be captured and sent by the device, but the client would ignore it because it could not play audio). In that case, it must be disabled explicitly.

fix解决

我使用的是一加手机和win7系统，我解决了这个问题。如果你们遇到类似的问题，你可以试试我的方法。
我使用最新版本:scrcpy-win64-v2.2

I'm using a OnePlus phone and Windows 7, and I fixed the problem. If you have similar problems, you can try my method.
I'm using the latest version :scrcpy-win64-v2.2

start cmd启动命令如下：

scrcpy.exe --render-driver=software --no-audio

My computer does not have speakers. When I plug in 3.5mm headphones, the program no longer crashes. I suspect that the code is not compatible with this situation and directly throws an error, causing the program to interrupt. I hope it can be changed to a warning to be compatible with this situation. @rom1v

nickoe · 2024-04-18T08:53:33Z

Is it possible to not make this error fatal, such that we can continue to use the scrcpy even if audio hardware is disabled in windows?

rom1v · 2024-04-18T09:29:55Z

Not automatically: #4800 (comment)
You must pass --no-audio-playback explicitly.
