Can't open audio device /dev/dsp: Device busy

[Tuc at T-B-O-H]

Hi,

	Running a pretty current 4.11-STABLE, my pcm is 

toshiba# dmesg|grep pcm
Preloaded elf module "snd_pcm.ko" at 0xc05f81dc.
pcm0: <Yamaha DS-1E (YMF754)> port 0xfebc-0xfebf,0xfec0-0xfeff mem 0xefdf0000-0xefdf7fff irq 11 at device 12.0 on pci0
pcm0: <Asahi Kasei AK4543 AC97 Codec>

	and sndstat

toshiba# cat /dev/sndstat 
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <Yamaha DS-1E (YMF754)> at memory 0xefdf0000 irq 11 (4p/2r/0v channels duplex)


	When I first boot things are fine. I start GAIM with "Automatic"
and thats fine. But at some point it just stops working for GAIM and anything
else like mplayerxp. I start to get "Can't open audio device /dev/dsp: Device 
busy" but with fstat I get :

toshiba# fstat|grep dsp
toshiba#

	What do I do??

		Thanks, Tuc
