Slackware64 host, Windows 7 64 guest - audio problems

Reported by: redray8 Owned by:
Priority: major Component: audio
Version: VirtualBox 3.0.12 Keywords: alsa slackware windows7
Cc: Guest type: Windows
Host type: Linux

Description

Running Slackware64 13.0 as host, guest operating system is Windows 7 64-bit.

Tried all host audio drivers: OSS, PulseAudio, ALSA

Results: OSS/PulseAudio - choppy/crackling sound

ALSA - no sound at all, although the green bars show as if sound is being produced within the guest when running tests or changing volume.

Successfully installed Realtek 97 drivers and the device is working properly in guest Windows 7 devmgmt.

Here is the VBox.log when trying to use ALSA as the host audio driver:
00:00:01.661 Audio: Trying driver 'alsa'.
00:00:01.661 Audio: set_record_source ars=0 als=0 (not implemented)

Any ideas on getting ALSA to work properly or to get clear sound using OSS or PulseAudio?

Forgot to mention that ALSA host audio driver works flawlessly if the guest is Windows XP 32-bit.
