No sound from Laptop built in speakers

[Guest]

I get no sound or audio (including system sounds and beeps) from my laptop's
builtin speaker. Sounds work through headphones. I conceed that I may have a
hardware problem (like a blown speaker) but I don't have a good way to test
this.
I'm running XP Home/SP-2. Device manager shows all devices working, and no
(!) conflict flags. Everything is as updated as I can get from both MS Update
and Toshiba.

I uninstalled/reinstalled the built in sound card in Device Manager.

Nothing is Muted in Microsoft Master Volume Application. I have seen
references to an Advanced button under the Master Volume slider, but I don't
have this, whether File/Advanced options is checked or unchecked.

TweakUI has beep turned on.

I've been to Kelly's Korner (usually my first stop) and have downloaded the
relevant FAQ files and even the "ding repair" tool.

I think that somewhere, something is muting the sound in a way I can't
identify.

Any help would be appreciated.

I have experienced this today! Check with the laptop manual, or web site,
so as to see if the unit has special kets which allows you to "shut" the
internal speaker. I found this out on a IBM Thinkpad A31.

Yves;
I forgot to mention in my original post; my laptop does have a mute key, but
it is turned "on" (not muted.) So, good idea, but it can't be that.
Thanks for the response, though.

On some desktops the act of plugging a headphone or other device into
the front audio output jack literally disconnects the audio going to the
rear audio output. Something like plugging in the headset into an old
transistor radio if you are old enough to understand that reference.
Does (did) your laptop function that way or did it output to both the
headphone jack AND the speaker at the same time? If the headphone jack
did have a cutoff then your problem might be a physical flaw in the
headphone jack.

John;
I am old enough to understand the transistor radio reference. I had never
used headphone/external speakers prior to the discovery of this problem, so I
have no good way of knowing whether it's a "contact problem" within the
headphone jack. I suspect that it's a "mute" setting somewhere that I can't
easily find, but again, I don't know. Thanks for the response.
