Dear all
I am having problems with getting sound running well in Arch Linux guest (VirtualBox 3.2.8), the host is OS X Snow Leopard. The problem is that the sound is very choppy. I've checked around VirtualBox and Arch forums and it seems that some others experience these problems as well yet I could not see anyone sufficiently skilled to debug this paying attention. I think there is a problem with either VirtualBox implementation of the sound card or a bug in ALSA driver for that card because I have sound running just fine in VMWare Fusion (using es1371 (?) driver), so the host system definitely is fast enough for decent sound quality.
I would like to offer my help with identifying the cause of the problem and testing solutions if the need be.
I've attached my alsa-info output for your reference. Please let me know if there is anything else I could try to help.
I am very keen to help but I don't know how.
http://www.alsa-project.org/main/index.php/XRUN_Debug is a good start to see if the virtual machine does receive interrupts in the right time.
