XP Sound

[SlowSteve]

Apologies if this has already been "closed" but I cannot find a definative answer.

Does the sound work on an XP guest. On a number of hosts (Windows) an XP guest has juddery sound, I've tried just about everything with no luck. Is this just a long term problem or have I missed something obvious?

Thanks in advance

I'm listening to a classic rock stream right now in an XP pro guest "mplayer 11". Seems fine to me.
What are you trying to do?

Hi,
Skype, Media Player 11 and WinAmp. All run for about 15 seconds then it starts "juddering".
Host and guest showing virutally no effort in task manager and no "disk thrashing".

Like I said all work fine for me. Post the guests log file (as an attachment) and maybe we can see if there is an issue.

If you're using those applications at the same time, it may cause interrupt queues due to high latency and those will cause strange sounds. It's known that sound on guests aren't 100% perfect. That's why we recommend users to do as much as possible from the host just to avoid this. It is not good to have the other side stutter or sound garbled when using Skype, or they are missing parts you're saying.

I'm just using one at a time to test. The machine is doing nothing else.

Finally found the logs, being a real techiee they mean absolutely nothing to me.

Last log (I do hope these are what you meant).

I'm experiencing better sound using the Microsoft RDP audio driver than I received when I was using the virtual sound card implementation provided with VirtualBox.

I found out that I can get reasonably good sound from my XP guest by running the guest as a Remote Desktop Host using Microsoft Terminal Services. I access my XP guest in a remote desktop terminal session. To clarify, I'm not using the remote desktop implementation provided in VirtualBox. I'm using the one which is a part of XP Professional.

I have two network connections set up between guest and host. One of these is "Host-Only Ethernet". The other is NAT.

I'm not a network configuration expert by any means. But it seems to me as if the NAT connection shares my host's internet service with the guest, whereas the host-only Ethernet connection gets me into Remote Desktop (without the need of setting up port forwarding in order to use the NAT connection for both purposes).

When I first tried this, it made WMP, system sounds, and Adobe Flash better. However it made VLC worse, until after I changed VLC's output module from default to "win32 waveOut extension".

Hi All,
Many thanks for the help. In the end I re-built the VM from scratch. Problem solved, lovely sound.

Any idea what's actually different?

[SlowSteve]

Sorry, not a clue. Had no idea it would even work until it did. Base install was XP SP2, sound worked. About 600 updates later, inlcluding .Net and everything else and it still works. Can only assume that the original install went wrong without me knowing.
