I have Windows XP installed on a virtual machine, and I like to set my Master and PCM volume to 100% and not having mess with it afterwards. But when the virtual machine starts, it automatically changes Master and PCM volume, and I have to manually readjust to my liking. Even when I set all the volume levels to 100% on the VM, the host changes to a much lower volume. (100% for alsa and for windows are very different) I think it is a more sensitive approach to have the guest not being able to change the host volume by default. Reproducible: Always Steps to Reproduce: 1.Set PCM and Master to 100% 1.1 amixer set Master 100 unmute 1.2 amixer set PCM 100 unmute 2.Run a Windows VMWare guest 3.run 'amixer' and check that Master and PCM volumes are lower. Actual Results: Master and PCm volumes are lower Expected Results: keep the Host configuration 'as-is'
I had started a thread: http://forums.gentoo.org/viewtopic.php?p=1852751#1852751 A partial solution for the Master volume is to add this to the virtual machine config: pciSound.enableVolumeControl = "FALSE" We need to change the .vmx file by hand, though. PCM volume was still lowered to 39%.
This is totally a VMWare issue with their software. Take it up with them, honestly.
