Hi -hackers, Several people have made it known to me that games such as Quake2 which ran fine with sound under the 4.2 kernel are not able to have sound in 4.3. I have verified this myself - with quake2 under 4.3 ktrace reports that opening /dev/dsp fails with EBUSY - even though nothing is using /dev/dsp and other programs are able to open it and play sound just fine immediately afterwards. Under 4.2 on the same machine, open()ing /dev/dsp is successful and sound functions. Figuring out what's going wrong is further complicated by the fact that these are linux binaries and run under the linux emulator. Could it be the linux emulator messing something up, and not the sound card? Since this is an issue of the userland's interface to the sound driver and is not concerned with sound driver internals or driving a specific card (since this problem occurs regardless of sound card), I thought I might try and see if could fix the problem. I've not done any kernel programming before, but I'd like to get my feet wet and this seems like a relatively small project. Any pointers as to where to start? Anybody else run into similar problems and try to see what is going wrong? -- farooq <fmela0@sm.socccd.cc.ca.us> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
