ALSA Sound Problem. Laptop plays both outputs at once.

Okay, so I've had alsa installed as my sound driver for a while on my Compaq Presario V3000 laptop. I believe it uses the Intel HD/Conexant Audio device or something. Anyway, whenever I have to use my sound for playing music or whatever, I have to manually change the volume for either the headphone jack or the built-in speakers. In other words, the alsa system sees my two outputs as separate streams. So if I plug in my headphones, the speakers still play unless I mute the speakers and I still have to turn up the volume on my headphones after that. Most systems seem to use the combination of speakers and headphones as one unit, depending whether or not there is a jack in the headphone jack. When I tried Ubuntu a quite a while ago on my laptop, the sound system worked in the manner I expected and my lighted up buttons worked to change the volume (I can't seem to make them work with gnome). I don't know why my sound is so strangely set up, but does anyone know how to configure it so that these weird sound problems don't make switching to headphones a hassle? Thanks in advance to any help. I've only seen one guy with a similar problem and he was strangely using my laptop on ubuntu.

What devices do you have under /dev/sound?

These are my devices under /dev/sound:

[code]localhost nightowl # ls /dev/sound/
audio dsp mixer[/code]

Thanks for your help.

I had the same problem. Make sure your card is being detected as the right model (check dmesg) and more than likely both sources will have their own volume meter. Example: my card is the 3stack-dig model, and "Front" controls the speaker and "3D" controls the headphone jack (I haven't figured out what's up with that yet

)

Is this 'problem' possible to be achieved with most sound cards? It would be cool to have four speakers on my laptop and therefore 3D sound!

Well, my dmesg shows only one ALSA device, but I will print the parts I think are applicable.

Those are the parts I believe have anything to do with my sound. I would like to also note that my driver is compiled straight into the kernel instead of modularized, if that will help at all. Sound configuration is one of the few things I don't really know much about in linux. sonicbhoc, did you find a way to make the ALSA system recognize your device as one thing? I believe we have a similar issue, that ALSA is treating our sound as two separate devices, instead of one. Also, InvalidComponent, I believe you are mistaken about what the "problem" is. I don't get 3D sound, I just get the same sound coming out of my headphones and speakers at the same time.

For sake of the thread, here's the solution to your unknown symbol issue. From the ALSA guide(though it may not have been there when you originally posted this)
