/dev/dsp missing? (SOLVED)

**Weedman** · 02-27-2006

Hi all again.

I have had gentoo set up on my lappy for about a week now with no issues relating to this, but when i tried to play music this arvo, both snackamp and mpg123 complained that /dev/dsp is missing.
well actually snackamp complained about /dev/mixer & mpg123 about /dev/dsp.

i am sure i didnt change any settings relating to /dev/dsp & /dev/mixer. a quick search in /dev dir reveals that i have no /dev/dsp, /dev/dsp1 and /dev/mixer.

i do have /dev/dsp2 and /dev/dsp3 though.
what is going on? may this have anything to do with the fact that i have been unable to get alsa to save its volume settings as "alsactl" does not exist?
thanks guys

when you emerged the alsa drivers did you also emerge alsa tools, alsactl is a function from alsa tools I think.

a second check reveals that /dev/dsp and /dev/mixer are only required for oss, not alsa. i set xmms to output thru alsa, and it worked.

2ndly, alsactl does exist, but only as root, and does not restore the sound for me as a user (not root).

yeah the alsa dsp is located in /dev/sound/dsp if you want oss emulation then enable that in your kernel as some programs still require oss to work.

but you see, i did enable oss emulation in the kernel. unless i put it as a module. ill check my kernel configfile. but i do remember /dev/dsp existing when i installed mpg123, now it complains about it missing.

Thanks spencerf

EEK! dont enable oss in the kernel that will block alsa!! from loading. to enable oss emulanion you simply add

Code:

oss

useflag in

Code:

/etc/make.conf

then if using alsa-driver recompile the driver or if kernel alsa simply recompile the kernel

I wasn't actually suggesting that he enable OSS in the kernel. Only the emulation stuff located under alsa.

Code:

<M> OSS Mixer API      [*] OSS Sequencer API

oh well, i will use alsa for xmms and mpg123.

i already use alsa for xmms, so i mightas well use it for everything else.

thanks guys, that gave me a bit more of an understanding of oss.
