Welcome to Linux Mint s418woods - how did you hook into linux mint? What version on mint are you using (main, kde, xfce)? Did you install and keep the home partition you had in mepis?

In spite of the aprox 20 minutes time delay between the two answers I did not see it before I posted - odd and gives a somewhat strange effect :lol:

Ummmm...what the heck?
Sounds not working for me as well, so I thought I'd read this topic for help.
Confused me even more. :(
Help?

sticknam50392 - We would still need the same questions answered ... no sound at all ... and is this a fresh install, i.e. - did you start with another distro and keep the /home partition from that install? Other things:
is it on-board audio (motherboard mfr), a sound card, etc.
At this point there isn't much to go on. For example, once I lost all audio, but only on only the applications like media players. It turned out that all these apps had to have the same output plugin.

Uhh...let's see...
I have an HP Pavilion dv6500t.
I don't have sound at all (start-up sounds, Pidgin, music, video, etc.)
I had Vista installed on my computer before installing Mint, but nothing else.
And that's about all I know about my laptop...
Sorry. -_-

Hi there,

One of the advantages of being based on Ubuntu is that sometimes solutions to Mint problems can be found in the Ubuntu forums. Below is an Ubuntu link relevant to your computer. I have a HP dv2000t series, and sound is an issue. Check the Mintu HowTo forum for my comments on sound with my HP laptop.

https://wiki.ubuntu.com/hp_dv6000_series_%28dv6116eu%29?highlight=%28dv6000%29#head-dd3315017e3efc368510f9b2b7022f8aeb15451e

Best regards

John -
Thank you so much for directing me to this guide, I'll be sure to search it before posting on this forum.
However, the only audio-related help I could find with it was for the headphone jacks. Right now, my computer doesn't play any sound at all.
Any help or suggestions?
Thanks in advance,

This works for me, reboot and let the os load all the way to the desktop, then turn the power off at the power supply, let the computer shut down completely now reboot, this works for me evertime, hope this helps. this also works on ubuntu 7.10 :D

Safe - yes and no. Not to recommend.
It's safe if "nothing is going on". If this is not the case you may get severe write errors to the hard disk - depending on the quality of the disk. Good disks should write everything in their cache memory even after power is turned off (the spinning disk makes the motor into a generator).
But all data in RAM is lost and possibly something should be written to logs etc which does not happen.
In essence - you don't destroy your PC but you can cause logical errors that may be hard to fix

Gahh.
I don't fully understand the consequences of that...but they don't sound good....
So does anyone know a better, more recommended way to do this?
Thank you all so much. :D

Things are getting a bit out of tune here.
Sometimes the sound works and sometimes it don't.
After I reboot(re-start) my system no sound, reboot again, one or a couple of times, there is sound. Over and over again.
I think something is wrong, probably with me, but is there a solution for this?

Cheers

Hi folks,
Here is a reply I received on the ALSA bug site. Seems to be in the same direction that s418 Woods responded. I haven't looked at my system yet but will do, to see what is there.

Hi JohnH and everyone who cares,

yesterday I installed the original SuSE kernel 2.6.22.5-31-default (from
DVD) as an alternate boot kernel. I did this manually by extracting the
files from RPM and copying the files to their destination location. (Seems
that Yast does not support installing alternate (older) kernels ).

And belive it or not, this was all I had to do and after a first reboot
(still booting the newer kernel 2.6.22-12-default) sound was back.

There was no obvious reason for this. First I finished alternate kernel
installation (grub, initrd and depmod) and then I tried to find out what
happened. But on next reboot, sound was muted again, regardless which
kernel I was booting. Restarting alsa at runtime did not help.

I found that there is one file in the rpm of kernel 2.6.22.5-31-default
which is now in use by both kernels: /etc/modprobe.d/module-renames. The
depmod -a (running 2.6.22-12-default) created new module dependencies
including this file). Maybe this muted sound again?

Commenting out everything in this file and updating dependencies : sound
still muted.
Undo comments but not updating dependencies : sound is back again.
And sound is back again for both kernels!!

So for now all I can tell is that it does not look like a kernel bug.
Either no sound at all or sound from both kernels. Seems is has to do with
module dependencies.

But I am still not convinced completely. Yesterday evening, I did not have
enough time to test all the combinations several times and see if behaviour
is reproducible.

Is there anyone with a better guess?

Best Regards,
Klaus Hi

This might be of help to some of you.

Regards
John
