Sound test error "Corrupt Audio input"

[Smartmatic]

CPU : Intel Celeron(R) N3060
RAM: 2G

BurnInTest version: V3.4

It just beeped from speaker and occurred "Corrupt Audio input" error message after executed sound test case.

Could you please on it?
Thank you very much.

Are you using an audio loopback cable?

[Smartmatic]

No, it is just two PIN out (Picture 1) and we also need to test the small speaker (Picture 2), so we connect them together.

[David (PassMark)]

The audio loopback test expects the audio output to be looped to the input.

I checked the BurnInTest preferences.
In Windows version, it can select standard or loopback test.
In Linux, It just has loopback test.

Does it have any way to set it to standard test in Linux?

Thanks.

No, only the loopback test is available in BurnInTest Linux.
