[Solved] Microphone not working with Guest Windows 7 virtualBox

Post by PRGMinds »

Team, I just started using Virtual Box and did setup for Windows 7 on Host . I am getting Sound out of it, but unable to use my Microphone there.

Virtual Box 6.0
Windows 7

I already checked the "Enable Audio Input" but still not working.
I tried to change Audio controller from default Intel HD Audio, but other options creates issue even with Audio output too.

Please advice something onto this, as I want to use this Virtual Mchine for some recording purpose.

Please provide a VM log file. Make sure the VM is fully shut down, then right click it in the manager UI. Select "Show Log" and save "VBox.log" (no other file) to a zip file. Attach the zip here.

A log file is a necessary part of getting an answer, but doesn't necessarily mean that I have that answer. However I do see that your VM is not configured for good performance, so perhaps that is affecting the audio.

The notes I have are:
  • You are using an old and unsupported VirtualBox release on an old and unsupported host OS.
  • You are stretching the resources of the host PC by assigning too much RAM to the guest OS. I would cut the RAM allocation to 2048MB.
  • No modern OS runs well on one core. You may simply not have enough CPU to capture audio smoothly. I would increase to 2, although the 2 core host is not ideal for this.
  • You should install the extension pack on the host.
  • You are running from drive D:. I'd like to know what kind of drive that is, e.g. local hdd, local ssd, USB mechanical, network drive etc.
  • Eject the Guest Additions ISO.
  • The log shows that Intel HD audio is still being used.
  • Your audio settings seem to be identical to my own Win7(64bit) VM, including the use of Intel HD, and mine works just fine (for output, I don't use a microphone in my VMs). Perhaps some kind of mixer settings problem in guest or host?
  • If you have the microphone input selected inside the VM, try "Line In" instead.

Sure, we can mark this as resolved. Point I took for this resolution:
1. Upgraded the OS(I guess, this was the key)
2. Upgraded Vbox as suggested by mpack
3. Increased the CPU core to 2
4. Line In was already opted
5. Reduced the allocated RAM to 3gb.

I've just had this issue and found a solution at {obfuscated url deleted}
2 points to add though
1. After running setup.exe and rebooting my device was not working in device manager. Right click on it, choose update driver and browsing my computer to the unzipped driver folder resolved this
2. |Don't forget to

Code: Select all

run bcdedit /set testsigning off
and reboot afterwards.

URLs from first time posters are regarded with a touch of suspicion, so they need to be essential. We generally don't consider offsite solution links to have authority (this site is the authority, along with the user manual) - especially in a topic that was already marked as solved.
