howdy! I am new to linux. After talking with a friend and playing with a live cd for a while, i decided to install Kubuntu. I made a mistake of not trying to play music during my trial period. My sound does not work.
I opened Sys. Settings and tried the ALSA. didn't work. also in the command prompt when i tried to do a MAN for it, no alsa commands availible.

any help would be greatly appritiated. Thank you!

Admittedly, I do not know much about Toshiba laptops, but with gateway and some older dells, they use ISA based sound (believe it or not) and if so... it will difficult or next to impossible to get it working right. Is this a newer laptop or older? Have you google'd for linux drivers for your laptop?

I'm with you on this one. Just bought a Toshiba Satellite A205-S4577. Fedora 6 and 7 installed on it, plus have tried many live distros, no sound. But I think that the real issue is no sound VOLUME. MP3's play in all the media players, I just can't hear them.

Without more details, it's not entirely possible help you, but I can make some general solutions. If you have tried all the common options for your card (adding auto, 3stack, etc) and none of them work, what you will have to do is upgrade your version of ALSA.
If you post the details of your lspci -vvv (audio section only) and /proc/asound/card0/codec#0 (everything until Default PCM), I can give you more detailed instructions on what to do.

hi have a kinda similar issue. I have a toshiba a135-ss286 sound was ok with fedora core 6 then i installed fed 7 which had no sound until i updated the kernel and alsa, only one problem my headphone jack isn't working. any ideas

Try alsamixer in an xterm, or console. Use tab over to the PCM bar and up arrow until the bars are in the green zone.. then do the same with the speaker bars.

then do alsactl store to save the settings. When I reboot from power outage, I lose sound and have to do
alsactl restore

to restore the settings. I'll have to figure out how to link that alsactl command into
the /etc/init.d startup stuff..

As it happens I just got an A135-s4427 myself. The first thing you have to do is positively identify your sound chip, you could have one of several. The output of your lspci should tell you this.

I am running Slackware so the details for your distro may vary, but all I actually had to do was to modify a config file to make sure that the modules for my soundcard was loaded. In my case I added a line:

/sbin/modprobe/snd-hda-intel model=3stack

Note that model=3stack works for my chip. When I was googling trying to figure the issues out there were three or four other options that worked for other people depending on their specific chip.

Once that was module was loaded it was as simple as running alsamixer, and then storing the setttings.

For volume, there are no known fixes (that I am aware of yet). My machine anyway does not use a 'standard' volume switch. It is a sensing type. As a matter of fact whether I have headhphones plugged in or not, the laptop always plays out of the speakers and the headphones.

All other major elements of the hardware are working fine though including the media card reader.

i Have a similar problem for my soundcard (HDA-Intel). I used ubuntu 7.04 (feisty) on my toshiba sat. a135-s4427.
its seem the sound player (totem and other) work correctly, but i didnt hear a sound at all
I tried to compile the latest stable kernel(2.6.22) that i downloaded from www.kernel.org (with various compilation option) but it just not work (event worst, because the volume manager didnt detect my soundcard).
Finally, i tried to downgrade my ubuntu box and install Ubuntu 6.04 LTS (Dapper), it soud silly, but it work well
But the kernel itself have a bug (PCI #81 bug).

I am using Toshiba A135-S4656. The sound works out of the box after Ubuntu 7.04 using 2.60.20-16-generic kernel. Have you tried with restricted-modules? What does your dmesg says? My sound is Intel.
