Headphone output Fedora 14

[tm2383]

Hi,
I am having an unusual problem with my Fedora 14 install. If I start Fedora with no headphones plugged in, the sound works fine on You Tube etc. Sound comes out Headphones AND speakers if i subsequently plug in head phones. If I start Fedora with headphones plugged in, headphones work, but I get no sound through computer speakers when I unplug headphones. Strange.
Output is RS880 Audio Device [Radeon HD4200] with Digital Stereo (HDMI) output set

Thanks,
Tim

Perhaps you could provide more detail on your audio hardware and software configuration ? You can do that by running with your PC connected to the internet a diagnostic script :

/usr/sbin/alsa-info.sh

and select the SHARE/UPLOAD option. That script when complete will give you a website/address/url where the diagnostic information from your PC was uploaded to the alsa web site. Copy that webside/address/url and post the address here.

That way the guru's on this forum can take a look at your configuration and maybe that might yield some clues.

I'm getting a no such file or directory error when I issue that command.

I'm running Fedora 14 64 bit. Sound is provided by ATI RS880 audio drivers according to output from LSPCI.

Further information:

[root@localhost tm2383]# head -n 1 /proc/asound/card0/codec*

Codec: Realtek ALC272X

When I run alsamixer, everything looks ok.

Don't know why it isn't working.

Thanks for the reply,
tim

It would surprise me if Fedora 14 removed that command.

Did you physically LOOK with a file manager to see if the directory /usr/sbin is in place and if the file 'alsa-info.sh' is inside that directory ? If it is there, then you made a syntax error and need to type the command again.

/usr/sbin/alsa-info.sh
