Help with audio (alsa)

Postby md1011 » 7. Dec 2017, 15:59

Host = Ubuntu Server 16.04.3 LTS
RDP Host = Windows 7 Enterprise SP1 x64
Guest = Windows 7 Enterprise SP1 x86

VirtualBox 5.2.0r118431

I followed the steps in the AudioDebug wiki, but the .WAV files that generate are all 44 Bytes with nothing to play. When I play audio on the guest, you can see the activity in the Volume controls, so my thought is that my driver set-up on the guest is correct. Thanks in advance for anything you can provide.

They're actively working on the audio. Try the test builds and see if there is any improvement. Otherwise you'll have to wait until more fixes come in.
Do NOT send me Personal Messages (PMs) for troubleshooting, they are simply deleted.
