Have been beating my head on this for a while with no success...
I have an Oracle Linux host (5u6, kernel 2.6.32, x86_64), running a user-specific pulseaudio server daemon. Running paplay /usr/share/sounds/phone.wav produces sound, as expected.
VirtualBox 4.1.12 / Windows 7 guest is running, configured to use pulseaudio interface with Intel HD emulation. No sound from the windows guest.
No errors reported neither by Vbox nor by Windows: both report functioning "hardware". The vbox log does show an error: "HDAcodec: can't open out fmt(freq: 44100)". Please, see the attachment to see all of the messages related to Audio.
pulseaudio daemon (running with level 4 logging level) does report connections with the Vbox instance, same exact messages when using paplay successfully (please, see the attached log file). I deduce that Vbox indeed is connecting to the PA daemon, as expected.
strace of PA daemon shows no activity whenever I attempt at playing any sound on the guest, while it does show plenty of activity when using paplay. This tells me that the signal from guest does not make it through the Vbox emulation.
tried using AC97 emulation for the guest - no success
Could anyone please give me some more ideas for solutions? Any way to troubleshoot this in the Vbox itself?
