[SOLVED] Sound on IBM R50e thinkpad

ajitabhpandey · 05-23-2006, 10:15 AM

I am running slackware-current on an IBMR50e thinkpad. Surprisingly there is no sound. Following are some outputs, file perms etc. When I run mpg123 I get "can't create mcop directory" error (even as root). When I run xmms, I dont get any error but I dont hear anything either. On xmms (or real player) the file looks to be playing normally, but no sound.

Any help will be appreciated.

This might be the swapped sound card and modem problem, which snd-intel8x0m seems to trigger sometimes.

ajitabhpandey · 05-24-2006, 07:15 AM

So what needs to be done in order to fix it. Tried live CDs of Ubuntu, Knoppix and even installed Debian on a small partition and all gave sound, except Slackware. Any ideas. Will an upgrade to 2.6 can fix it. Dont want to upgrade to 2.6 unless absolutely essential.

Alien Bob · 05-24-2006, 08:21 AM

If it is the modem that is in the way, add a line containing "snd-intel8x0m" to the file

Code:

/etc/hotplug/blacklist

Slackware 10.2 should have that line already btw.

The "can't create mcop directory" error looks like the permissions to the /tmp directory are messed up, and/or there are existing subdirectories there where the permissions are messed up. Permissions on /tmp should look like this (run ls -l /):

Code:

drwxrwxrwt  151 root root  12288 2006-05-23 23:06 tmp/

and you can correct messed up permissions by running

Code:

chmod 1777 /tmp

ajitabhpandey · 05-24-2006, 09:22 AM

The perms on the /tmp is ok

Code:

$ ls -ld /tmp
drwxrwxrwt 11 root root 640 2006-05-23 22:44 /tmp

As for snd-intel8x0m, although my thinkpad does not have a modem so dont know why this module is there is its required by a modem, but I have put that in the blacklist file.

However for now I have manually removed it using rmmod command. Still the same result. (or do I need to reboot the laptop..., will do it anyway when go home)

Figured out finally. A possible bug and since I was using current, I was the unlucky one to hit it.

I did the following

Code:

$ mkdir -p $HOME/.kde/socket-`hostname`

and then

Code:

$ mpg123 Choote_Si_Zindagani.mp3
High Performance MPEG 1.0/2.0/2.5 Audio Player for Layer 1, 2, and 3.
Version 0.59q (2002/03/23). Written and copyrights by Joe Drew.

[0:12] Decoding of Choote_Si_Zindagani.mp3 finished.

and also just to check whether the module which I unloaded has any effect on this I did:

Code:

$ sudo /sbin/insmod snd-intel8x0m
Using /lib/modules/2.4.32/kernel/sound/pci/snd-intel8x0m.o.gz

$ lsmod |grep snd-intel8x0m

Yes, the modem driver takes the 1st slot in the audio drivers and is therefore the default soundcard until you reboot (or restart ALSA I guess).

But, if you do need the modem driver and are not able to blacklist it, there is a way to force the modemdriver to second place so that the "real" sound driver will be the default for your sound output. For that to happen, you should re-arrange your ALSA configuration in /etc/modules.conf or /etc/modprobe.conf or /etc/modprobe.d/alsa so that it looks like this (the index is what does the trick here):

Code:

# --- ALSA configuration ---
alias char-major-116 snd
alias char-major-14 soundcore
alias snd-card-0 snd-intel8x0
alias snd-card-1 snd-intel8x0m
# --- OSS Compatibility
alias sound-slot-0 snd-intel8x0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
#
alias sound-slot-1 snd-intel8x0m
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-12 snd-pcm-oss
# --- Options
options snd major=116 cards_limit=2
options snd-intel8x0 index=0
options snd-intel8x0m index=1
# --- End of ALSA configuration ---

I'm putting this thread in my bookmarks, because once in awhile, my modem does the same thing (takes over alsa after a reinstall). Thanks for that stuff, Eric.
