Sound problems

[bmn]

Host Windows 7 x64 SP1 with all others update.
Guest Windows 7 x64 SP1.

Problems:
The system sounds are truncated just before they finish.
Also, if you test the speakers (Control Panel - sound; double click on Speakers, select tab Advanced, click on Test) the resulting sound is very bad: is croaky.
The problem do not appear on VirtualBox 5.1.2

Here more details about this matter regarding Virtualbox versions and the concerned platforms:

    HOST    - VBox version - Sound status
 Mac 10.11  -     5.1.4    - broken
 Mac 10.11  -     5.1.2    - broken
 Mac 10.11  -     5.0.26   - ok
 Windows 10 -     5.1.4    - broken
 Windows 10 -     5.1.2    - ok
Ubuntu 16.4 -     5.1.4    - broken
Ubuntu 16.4 -     5.1.2    - ok

The audio controller used on all platforms is ICH AC97. The sound is croaky and randomly no sound at all. We just tested the speakers, not the microphone.

VBox.log from tes build of 5.1.5 of test session with skype. incoming voice was with skips. host ubuntu 16.04, guest windows 10

This is still an issue in 5.1.6 release version. I have no sound at all with a fedora 24 guest on Win 8.1 host.

I've gone back to 5.0.26 which fixes the problems, but I sacrifice USB 3 support due to the Linux kernel bug which 5.1.4 worked around.

I can confirm this happening with my setup as well, but the circumstances are a bit unique. Although I'm running Windows 7 x64 on the host, the client(s) are Windows 2000 Server. =-)

The symptoms are the same as others have described above: any sound played in Windows, regardless of the player software, gets truncated by a fraction of a second. Also, I can confirm it's not just WAV files, but MP3 files as well, so it doesn't seem isolated to a particular filetype either.

Version info is below. Plz let me know if there's any other info I can provide. Vbox: 5.1.6 r110634 (Qt5.5.1) Win2k: 5.00.2195
