[Qemu-devel] Audio errors without setting "-soundhw"

[Andrei Dinu <andrei.adrianx.dinu@intel.com>]

Hello qemu-devel,

I've been trying to run an arm image with these parameters :

sudo 
/home/adinu/work/poky4/poky/build/tmp/sysroots/x86_64-linux/usr/bin/qemu-system-arm 
-kernel 
/home/adinu/work/poky4/poky/build/tmp/deploy/images/zImage-qemuarm.bin 
-net nic,vlan=0 -net tap,vlan=0,ifname=tap0,script=no,downscript=no -M 
versatilepb -hda 
/home/adinu/work/poky4/poky/build/tmp/deploy/images/core-image-sato-qemuarm.ext3 
-no-reboot -show-cursor -usb -usbdevice wacom-tablet -no-reboot -m 128 
--append "root=/dev/sda rw console=ttyAMA0,115200 console=tty 
ip=192.168.7.2::192.168.7.1:255.255.255.0 mem=128M highres=off "

and i keep getting these errors :

oss: Could not initialize DAC
oss: Failed to open `/dev/dsp'
oss: Reason: No such file or directory
oss: Could not initialize DAC
oss: Failed to open `/dev/dsp'
oss: Reason: No such file or directory
audio: Failed to create voice `lm4549.out'

behavior which is not normal without setting the "-soundhw all" parameter.

When running a qemu-system-i386 image with these parameters :

sudo 
/home/adinu/work/poky4/poky/build/tmp/sysroots/x86_64-linux/usr/bin/qemu-system-i386 
-kernel 
/home/adinu/work/poky4/poky/build/tmp/deploy/images/bzImage-qemux86.bin 
-net nic,vlan=0 -net tap,vlan=0,ifname=tap0,script=no,downscript=no -hda 
/home/adinu/work/poky4/poky/build/tmp/deploy/images/core-image-sato-qemux86.ext3 
-show-cursor -usb -usbdevice wacom-tablet -vga vmware -no-reboot -m 128 
--append "vga=0 root=/dev/hda rw mem=128M 
ip=192.168.7.2::192.168.7.1:255.255.255.0 oprofile.timer=1 "

i get no errrors. I get them only when i add the "-soundhw all" 
parameter, which is a normal behavior.


Does anyone know why the errors keep coming up at the arm build without 
setting the sound parameter? Do i have to unset some default variable?

I am using :

Thank you,
