Description Marius Andreiana 2005-08-17 15:38:43 UTC 
This is a followup from bug #144742

"External Amplifier" is off by default, and this causes my laptop speaker to be
off no matter what the volume sliders are. With headphones it works.

Expected results:
By default, "External Amplifier" should be on.

Comment 6 Marius Andreiana 2005-08-17 15:42:49 UTC 
I don't have "Headphone Jack Sense" in alsamixer as other people reported in
#144742, but it shouldn't be mute too.
Comment 7 Martin Stransky 2005-08-23 14:28:53 UTC 
External Amplifier was unmuted in rawhide. If anybody need to unmute the
"Headphone Jack Sense", please reopen this report.

Shifting the version from fc4 to fc5..

Could you clarify what you mean by "unmute Headphone Jack Sense" ? (In
particular, what "unmute" means in this context -- I wasn't able to figure out
which setting is "mute" and which is "unmute"..)

I have FC5 with kernel-2.6.18-1.2189.fc5 on Thinkpad X31, with:

00:1f.5 Multimedia audio controller: Intel Corporation 82801CA/CAM AC'97 Audio
Controller (rev 02)

.. and couldn't get sound to work with aplay, etc.  I even upgraded alsa to
1.0.13 and no luck.  The only thing that worked was pcspkr (beeps etc.).  The
result was the same whether internal or external speakers were connected or not.

When I turned off "Headphone Jack Sense", both internal and external speakers
started working.

Maybe this means that at least in some cases "Headphone Jack Sense" is not
configured correctly?

"Headphone Jack Sense" is turned off by default in fc-6/rawhide so it should
work there.
