Description

This is hrev32435, gcc4-hybrid in VirtualBox 3.0.4.

If I use ALSA, ICH AC97 as VirtualBox's audio setting, 3 threads of the media_addon_server (Auich ICH control, multi_audio audio output and Mr Power's Yeah, baby, very shagedelic) suck ca. 30% CPU.

(Using ALSA, SB 16, there's no suckage, but there isn't any audio device found either. With ICH AC97 there's at least an audio device present, though there still is not sound.)

I'm using VirtualBox 3.0.4 and it set to ALSA and ICH AC97, but media_addon_server don't suck any CPU at all.
Sound have metallic effect, though.

Still there is a bug with Haikus ac97 driver for VirtualBox. When using Windows or Linux as guest os there is no problem with the sound at all, but with Haiku, like you said you get a metallic effect.

BTW, OSS is working fine as long as you remove auich driver.

Not much CPU suckage with alpha3 in VirtualBox 3.2.8. Thread "multi_audio audio output" is at 5%, but I guess that's OK. Still no sound with ICH AC97, but I don't feel like checking out OSS. Closing ticket as fixed.
