Default Can't turn off laptop speaker

My Intel HDA (ALC883) works fine with OpenBSD, but for one problem: the laptop speakers won't shut up, and there doesn't seem to be any channel or switch to control them. How can I turn them off? Are there options I can pass to the kernel or something?

This is vague, but there is work going in -CURRENT on azalia(4).. if you were following the mailing lists you would have known about this.

http://marc.info/?l=openbsd-tech&r=1&b=200811&w=2

One relevant topic would be this..

Now, another option (if you don't want to follow -CURRENT, which is kinda advisable with laptops..) is to simply lower the volume levels with mixerctl(8).

In the future, please post as much information as you can... a dmesg.. mixerctl output.. etc.

Lowering the volume levels doesn't work, the output level from my speakers remains constant.

This is my dmesg output:

This is most likely a bug, do you mean your speakers are constantly producing an audio noise immediately when OpenBSD boots? or is the noise noticeable before that happens?

It could be either a hardware problem, or a driver problem... out of curiosities sake, try the following:

1) Set outputs.master.mute to on.
2) Use the UKC or config(8) and try disabling pcppi(4) or azalia(4), either could be causing this audio problem.
3) Boot and install a recent snapshot from a local mirror..

If nothing works, considering filing a bug report.. instructions are available here.

No noise, just normal sound output - if I play an MP3, for instance, it plays on my speakers as well as my headphones - but changing the volume of the various channels does not change the volume of the speakers' output.

(Said volume sounds roughly the same as that of the system beep, actually. Maybe if I turned off the system beep that would get rid of it?)

Ah, got it... outputs.surround.mute: off should have been on.
