Upgraded from Dapper -> Edgy, No sound in gaim or gajim

secretservgy · 10-30-2006, 08:43 PM

I just updated from Dapper 6.06 to Edgy 6.10 , i have fixed mode of the bugs. The only thing that is annoying me now is that there is no sound with gaim or gajim (a jabber/gmail IM client). I have problems with sound, such as every few startups sound wont work. But gaim and gajim sound used to work. There is also a problem with moc(p) in which none of my songs will play, it says that /dev/dsp is not accesable, but i can play them fine in amaroK. How can i fix this, i'm thinking they are the same problem? Thanks.

You need to set up DMIX software mixing. Google "dmix" and the first result is a great Debian tutorial.

That seems hard. I attempted it, didnt work.

It's not that hard. First just run

Code:

apt-get install alsa-oss alsaplayer mpg321 alsaplayer-alsa alsa-base

to install the necessary programs. Then test it out:

Code:

alsaplayer -o alsa -d plug:dmix pathtomp3.mp3 &
aplay -D plug:dmix pathtowav.wav &
alsaplayer -o alsa -d plug:dmix pathtomp3.mp3 &

If you can't hear all of them playing, there's some sort of problem. Next you set up your .asoundrc file.

Code:

cat > ~/.asoundrc << EOF
pcm.ossmix {
    type dmix
    ipc_key 1024 # must be unique!
#   ipc_key_add_uid false   # let multiple users share
#   ipc_perm 0666           # IPC permissions for multi-user sharing (octal, default 0600)
    slave {
        pcm "hw:0,0"      # you cannot use a "plug" device here, darn.
        period_time 0
        period_size 1024 # must be power of 2
        buffer_size 8192  # dito. It
       #format "S32_LE"
       #periods 128 # dito.
       #rate 8000 # with rate 8000 you *will* hear,
       # if ossmix is used :)
    }
    # bindings are cool. This says, that only the first
    # two channels are to be used by dmix, which is
    # enough for (most) oss apps and also lets 
    # multichannel chios work much faster:
    bindings {
        0 0 # from 0 => to 0
        1 1 # from 1 => to 1
    }
}
pcm.dsp0 {
    type plug
    slave.pcm "ossmix" # use our new PCM here
}
# mixer0 like above
ctl.mixer0 {
    type hw
    card 0
}

# You may want to make your new ossmix the default for alsa.
# If your alsa programs are complaining that they can't open
# your sound devices, try uncommenting this next line
#pcm.default pcm.dsp0
EOF

Now test out aoss:

Code:

aoss mpg123 pathtomp3.mp3 &
aoss mpg123 pathtomp3.mp3 &
alsaplayer -o alsa -d ossmix some.mp3 &

They should all play sound at the same time. If not, post what's happening.
