No sound from speakers in Feisty 7.04 - headphones OK

Please clarify whether you mean that sound via speakers is inaudible (whereas via headphones is audible) in 7.04. It's confusing to say "I have no sound...my sound works fine with the headphones".

Sorry - I mean that there is no sound at all from the speakers - although the headphones work fine. given that its a pain to sit there with headphones on - to all intents and purposes this means that I effectively have 'no sound'.

Hope this helps but if you need more details - lspci etc. then please let me know.

Steve

Not to be anal, but "no sound from speakers" is not the same as "no sound". What you're experiencing is a jack sense bug. Please attach, to this bug report, the information requested[0].

Please retest against 2.6.20-2 when it is available in the feisty archive.

Will do. I look forward to it (here's hoping!)

Many thanks for your time and effort.

2.6.20-3 is out now. Can you reconfirm?

Have just run the latest Feisty (12 Jan) and unfortunately there's still no sound.
Not sure what Kernel version it has, but still nothing!

Thanks for trying,

2.6.20-5 is out now. Can you please update and test again ?

To find out your kernel version issue this command in a terminal windows:
uname -r

A friendly reminder that 2.6.20-6.11 is now out.

Thanks for this, and for all you effort.
Unfortunately I am not running Feisty, but was just trying out the livecd in the hope that it might sort the sound problem. Will the new kernel be in the next release of Feisty, since this will be the only way I can try it?

Thanks again

Yes, please wait for the Herd-3 Desktop CD.

Steve, Herd 3 has been released. Could you please retest? Thanks

Have just retested, and unfortunately no sound.
Everything else seems to work ok though!

I am having an identical problem with my Toshiba Tecra M7. In my case, however, I notice that the sound through the headphones is quieter (as in much quieter) than Windows through headphones at the same volume. Through speakers, I find myself having to crank the amplifier a bit to get any good level of sounding to come through. Appears to be something in the system keeping the volume controls low and out of our conrol as I have everything in alsamixer and in the GUI's volume controls maxed.

For the record, I am running Feisty Herd 5 from a clean install.

Fix doesn't work for me.
Maybe sometrhing to do with bug 72908?

I'm assuming the 'fix' was in the latest kernel update 2.6.20.12?
If so, it stll doesn't work.
Do I have to do anything or would the update sort the problem?

I can confirm this bug on a Toshiba Tecra A8-ez8313 running Ubuntu 8.04 - the Hardy Heron with kernel 2.6.24-17-386.

I have to use the headphone port to hear any audio output. I can control it with the external volume toggle or the Volume control from the Panel. When I unplug the headphones, there is exactly ZERO sound coming from the two built-in speakers.

Adding the line:

options snd-hda-intel model=hippo

to /etc/modprobe.d/alsa-base

Should fix this problem for many people having this problem.
If not then you could try a different model.

Executing the following command in a terminal will append the above mentioned line to the end of the /etc/modprobe.d/alsa-base configuration file.

sudo echo "options snd-hda-intel model=hippo" >> /etc/modprobe.d/alsa-base
