No sound

[swappo]

Hello

I recently installed Ubuntu 7.10 and I have no sound. The sound icon in the right corner has a circle with slash through it. When I right click and select preferences, nothing happens.
lspci -v gives the following:

00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia
        Subsystem: Toshiba America Info Systems Unknown device ff0a
        Flags: bus master, slow devsel, latency 64, IRQ 16
        Memory at f8600000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: <access denied>

I am assuming that since my sound card was detected the driver is installed. I then typed the following:

$alsamixer

According to the following guide:

Comprehensive Sound Problem Solutions Guide - Ubuntu Forums

I was supposed to get a graphical equalizer, but instead, all I got were two boxes that I could select. One was Caller-I the other was Off-hook (sorry, not sure how to post the graphic). Not sure what this meant. I tried to find the driver at the alsa-project (still not sure if I need a driver) page and all I saw was an ATI SB450 driver and I am not sure if this is for SBx00 Azalia. I went into the Add/Remove Application and installed ALSA Mixer and still nothing. I am out of ideas. Any help would be greatly appreciated.

Try installing linux-backports-modules-generic

sudo apt-get install linux-backports-modules-generic

reboot and see if your sound works.

Hey Darkrose0510, thanks for the reply. I installed the linux-backports-modules-generic, rebooted and ran alsamixer from the prompt. I now have four controls for headphone, PCM, front and front mic. I unmuted the volume control in the upper right of my screen. None of which I could do before. All the volume levels are set on max and I still have no sound coming out when I try and play a cd. Any other suggestions? Also, according to the equalizer in the command prompt, I have an ATI SB card (which I already new) and a realtek ALC268 chipset (which I didn't know)

Okay, so I was finally able to get the sound to work. Here is what I did:
According to another post it said to edit the alsa-base file so I added the following to the last line:

options snd-hda-intel index=0 model=acer

The sound worked. However, I have a toshiba comp not acer.

The last response on the thread said to add the following for a toshiba:

options snd-hda-intel index=1 model=toshiba

This time the sound didn't work so I compromised and changed the index=1 to index=0 and the sound worked again. However, the sound is not very loud which was also stated in another thread. Anybody have any ideas as to how to increase the sound level? The other post didn't get that far. Also, does anybody have any ideas as to why this additional code got the sound working?
