I am running VMWare Workstation 5.5.4 on a CentOS 5.0 host (2.6.18-8.1.4 kernel) and I have been haiving some trouble with my sound device on the Guest Windows XP SP2 OS. When I first had trouble under CentOS 4.4, WS 5.5.3, it was usually when the sound device on the host was actually busy. However, now I can't use the sound device at all - I keep getting this error: "Failed to open sound device /dev/dsp: Device or resource busy Failed to connect virtual device sound." on EVERY attempt to connect to the CentOS native sound driver. I am running a few command windows, SeaMonkey and VW WS and nothing else. ps -ef reveals nothing about /dev/dsp and I'm not entirely sure where else to look. I had shut off the sound device (disconnected by default) because Windows likes to make noise and this routinely not only did not work, but it also kept interrupting everything I was doing with gnome windows announcing the above error. Now it just doesn't connect at all, no matter what the host is doing. Note: This is my work machine. At home I run VMWare Server 1.0.3 and only have this problem when the sound device is in fact busy (like I'm playing music or watching a video or something). I'd like to be able to run sound in the Windows guest.... -- Mark Hull-Richter DATAllegro (www.datallegro.com) 85 Enterprise, 2nd Floor, Aliso Viejo, CA 92656 Ofc: 949-680-3082 fax: 949-680-3001
