Checking to See what application has access to /dev/dsp

FunkyChicken

Hi,

I have been playing with wine, after i had finished the program and exited, i can not hear any sound from and application, i.e xmms, xine, etc. I am using OSS drivers, so only one can access /dev/dsp at a time. How can you check to see what application has access to /dev/dsp

P.S i did a ps -auwx | grep wine , etc to see if there were any zombie process es running, and there was none.

Thanks in Advance

Emerged lsof and it does exactly what i want .....

Thanks

Now i tried the wine application and reproduced the same problem (i.e after it has finished and exited i can not play any sound whatsoever - xmms says sound card busy), now when i do a /usr/sbin/lsof | grep dsp .... nothing shows up saying it is using the sound card at that time.

*NOTE*
I unloaded the modules (in this case modprobe -r i810_audio and modprobe -r ac97_codec) and started a sound app and the sound worked again.

Sorry, I forgot to mention you need to emerge lsof! Gentoo let's you compile and install everything, which is both good and bad. I was getting pissed off when I couldn't find "nslookup" and "telnet"... anyway. It sounds like wine might be locking up the driver, and then letting go of it, so the lsof command shows nothing but you still get no sound. At least you could unload the module, I've not been so lucky at times.
