No Sound


I have just instaled Mandrake 8.2 but do not have any sound on my Dell latitude LS.
The only info I could find on the net on it is

http://www.divisionbyzero.com/laptop/

http://www.geocities.com/atreshan/Archives/laptop.html

however, being new to the whole Linux thing these realy don't too much sence to me.
What I need is someone to either translate these to newbie for me or to give me another solution so I can have sound.

Thanks in advance !

no sound

I just installed linux (Icepack) and had a sound problem. I read a lot of stuff that didn't make any sense to me and tried many things that did not work.

However, finally sound started working. I don't specifically know what I did, but here is what I think I did:

First of all, I think maybe the sound volume might have been set to "zero". So, try calling up the mixer and checking the volume.

Second of all I re-ran the sound portion of the setup in the Icepack configuration manager. I imagine that you also have a windows type configuration manager of some type. The Icepack one is very easy to use.

I tried different driver/sound card combinations that seemed to relate to my sound card (which had been properly identified by Icepack in the first place).

There is an ALSA option and an OSS option (different types of drivers). I tried both, but you can not "turn on" both at the same time.

Also, from the KDE desktop, there is a "sound server" device to check the setup of the sound card/driver. I don't specifically know the problem, it would hang up. In fact, on one occasion, it didn't play the test sound and the program went into "hang" mode for a couple of hours. Then I managed to crash the Konqueror browser and as it crashed the test sound played.

The KDE desktop in Icepack has two or three different mixers. I tried them all and was more successful with one of them than with the others. However, they were not active when I did not have the sound drivers properly installed.

As you can see, I don't know a whole lot, but perhaps this might help.

Can you run a mixer?

If not, check permissions as follows: ll /dev/mi*

If owner/group are root/root that may be your problem. I had that situation. I have several other family members who might access the PC that I have added as users, so I first made a group "audio" and added all users. Then did: chgrp audio /dev/mi* and chmod 660 /dev/mi*. I may have changed the owner (chown newowner /dev/mi*) as well and done this for /dev/ds* as well (ds* ... dsp devices).

The main thing is that you should either be the owner or a member of the group that the sound devices are in. Then the "6" gives read and write permission. To have sound you have to "write" to the device.

If you don't know permissions, it goes like this: the first # is for the owner, the second for members of the group and the third is for eveyone else. Thus 660 gives read/write to the owner and to the group, but nothing to anyone else. A 7 means write/write/execute, 6 is read/write, 5 is read/execute, 4 read (technically of the 3 numbers is made of three binary bits so that 111 = 7, The first bit is for read, the second for write and the third for execute). The last number of the three should probably be 0, as I understand that there is a security risk in leaving sound open to anyone.

Hopefully I haven't made this so complicated that it confuses you more.

I can run the mixer I do not think it is a permission problem since I still have no sound as root.

harddrake?

Sorry, I haven't been able to get back to this and don't have too many ideas. It's been a while since I looked at Mandrake, but I think that the sound config is in the harddrake utility.

Maybe if you run that and note any specific errors someone who knows Mandrake might offer a suggestion. Maybe also try setup in Gnome and KDE both to see if it's something specific to one or the other.

Hope you find something that helps.

I had a problem with the sound server on Mandrake 8.2 and it ended up because 'full duplex' was selected. (Mind you, its an old sound card!)
