Hello ppl

I recompiled my kernel to 2.6 with ALSA support and all,

Now when i play music in xmms the sound is good for some moments then it starts craking and musics speeds up then it goes back to normal. Now this is quite annoying.

So i tried to change the output plugin in xmms from OSS to ALSA and here is the funnt thing.

When i start xmms as a normal user and change the output plugin from OSS to ALSA i can't play music anymore while when i start xmms as root i can change the output plugin to ALSA and then music plays with no error and no more cracking.

so, what do i have to change in order to use the ALSA output plugin as a normal user aswell ?

Thx in advance and have a nice day

hi,
did you set the permissions for the /dev/mixer* and /dev/dsp* device files correctly ?

chmod 666 /dev/mixer*
chmod 666 /dev/dsp*

i did what u did but still the same :/

tho when i start xmms from console i get this error

** WARNING **: alsa_setup_mixer(): Attaching to mixer hw:0 failed: Permission denied

cmon guy could u help me out here ?

i tried everything i looked even on post on anotehr forul and still the same ...

i tried chmod +rw , trying adding a new group only for audio still nothing :/

and that hw is says int in /dev/

hope to hear something ...

try
chmod u+s /dev/dsp
chmod u+s /dev/mixer

Still nothing


when root and i play a song i see in console :
Message: output format: 7
Message: fmt 5, channels: 2

Now after i've done chmod u+s as normal user i see along with the same error msg ofcourse:
Message: output format: 7

Before i didnt get any message as normal user, so i think we'r getting closer

Did you re-install alsa after you re-compiled your kernel? That had a big effect on my system.

If ALSA is set to use a pcm device then you need to:
chmod 666 /dev/snd/pcm*

This fix worked for me... I had the same issue.

slight

Wow!!!
I have identical problem. When I get home I'm gonna try changing permissions and see if it helps.

Don't know if your issue is solved yet, but one more thing you may try ->

# adduser <username> audio

I tried this aswell but still nothing :/

try dma 1


modprobe sb dma=1 irq=5

I did:
and i was able to use ALSA plug-in in XMMS. The sound now is MUCH better. No more speed-ups and that annoying noise that you usually hear when you have much more bass than speakers can handle. I still hear very quiet 'pops' when I play MP3s on XMMS. I didn't however hear those 'pops' with mpg321. I installed ALSA 1.0.0rc1, but popping is still there.
Also I'm still unable to use multiple channels at once, i.e. only one application can play sounds at one point in time (no mixing). I'm gonna try to figure out how to enable ALSA mixer plug-in dmix, something to do with .asoundrc, I think. Back to RTFM for now.

Cheers.

I know most people don't care, but the proper way todo this is to add your user to the sys group and not to chmod 666 everything in sight.

ZiGiE: Having the same problem as you are. XMMS works fine (meaning, no popping, can run as root/non-root), but whenever XMMS is running, other system sounds seem to "queue" up. When I quit XMMS, I get a barrage of pings, whooshes, and other system sounds for several minutes. If you figure out how to fix your problem with ALSA, please post your solution.

Thanks,
