[Bayonne-devel] cannot open /dev/dsp

[root]

Hello,

i am a newbie in Bayonne. Running Bayonne 1.2.6 with a soundcard (AC'97), i 
can hear no noise.
I got :
address@hidden root]# bayonne --soundcard playrec
tgi: initialized; uid=502 pid=1887
cdr: unknown keyword; tams(16)
import: unknown keyword; tams(19)
export: unknown keyword; tams(23)
export: unknown keyword; tams(28)
dummy(0): cannot open /dev/dsp
driver started 1 port(s)
normal startup; runtime configuration
dummy: start thread
scheduler: using /etc/bayonne.sched
*** press 1 to play or 2 to record...
*** enter the three digit prompt you wish to play...

No noise !
I think it is because of : dummy(0): cannot open /dev/dsp

Do you know where the problem comes from ? Any solution already encountered ,
?

Before getting to that point i wrote in DummyTrunk::DummyTrunk :
dev = ::open(devname, O_RDWR | O_NONBLOCK);
instead of :
dev = ::open(devname, O_RDWR);
,otherwise the system was blocked. 

When i use "dev = ::open(devname, O_RDWR);" i can unblock the system killing 
artsd but after i get the message :
"/usr/local/share/bayonne/UsEngF/sys/playrec/menu.au: cannot open"

Could anyone help to understand?
