[maemo-developers] [maemo-developers] Building own kernel: oss emulation

[From: Timo Steuerwald]

Hi all,


I activated oss emulation in my own kernel [1] and now try to use oss 
emulation about my usb headset [2], but the command prompt will 
immediately return if I give in  cat > /dev/dsp1 < /dev/dsp1 and press 
return. As I have taken a look on the devices I wonder because they are 
not character based as ls said:

> Nokia770-45:/sbin# ll /dev/dsp1
> -rw-r--r--    1 root     root            0 Feb 22 22:43 /dev/dsp1

I also tried cat /proc/devices, but the result doesn't contain /dev/dsp1

> Nokia770-45:/sbin# cat /proc/devices
> Character devices:
>   1 mem
>   4 /dev/vc/0
>   4 tty
>   4 ttyS
>   5 /dev/tty
>   5 /dev/console
>   5 /dev/ptmx
>   7 vcs
>  10 misc
>  13 input
>  14 sound
>  29 fb
>  90 mtd
>  96 dspctl
>  97 dsptask
> 108 ppp
> 116 alsa
> 128 ptm
> 136 pts
> 180 usb
> 188 ttyUSB
> 216 rfcomm
> 254 sticon

Anyone already tried that or any further clues?

Cheers,

Timo
