[CLOSED] acfax requires /dev/dsp /dev/mixer but they don't exist

[Rantanplan]

Hello,

I use Easy Dunfell 3.4.6 with a laptop toshiba.

I'll want to use acfax.
Acfax can to receive/decode fax from soundcard.

I install a package from debian repository (http://ftp.de.debian.org/debian/pool/ma ... _amd64.deb).
Anyone dependencie necessary, it seems.

acfax requires /dev/dsp and /dev/mixer, but they don't exist in /dev.

I tried to create :
mknod /dev/dsp c 14 3
mknod /dev/mixer 14 0

I symlinked /dev/dsp from a soundcard in /dev/snd. Possible, it is not a good idea.
But about /dev/mixer, what do I do ?

Can somebody to help me ?

Thanks.

Regards

You can't do it, the kernel has been compiled without OSS sound support, so /dev/mixer no longer works.

Most Linux distributions these days don’t even bother activating the OSS emulation layer present in ALSA because almost nobody needs it anymore, making OSS a relic of the past.

I understand.
