T61P / Fedora 12 64-bit / external audio jack not working


Greetings all - I have used Linux off & on over the past 8-10 years, and last fall went full hog (no windows partition left!) on my IBM/Lenovo T61P (model 6457-B51) and am currently running Fedora 12 64-bit. It's been SOLID since last October. I did bail to the NVIDIA driver and the video performance is fantastic as well for my work usage of this system.

I have sound through the internal speakers and also through USB headsets, so it appears that pulseaudio, hated as it is, is working fine on this hardware. However, I CANNOT get any sound through the speaker jack! I get a hum anytime I attempt to use speakers connected to that jack - I have not tried a microphone on the mic jack, so I cannot speak to whether that works or not. This came to a head when I tried to play an audio file during a class and could not get the sound into the room speakers.

Any suggestions/ideas? It's just odd that the OS is not able to talk to this port - this did work under Windows prior to my switch.

Worst case I guess I can find some USB speakers to use, but it would be handier to just plug into my guitar amp when I want some volume at home, and to be able to use other hardware as what happened last fall.

I also use a T61, and had similar problems.

Solved it this way:

open "System/Preferences/Advanced volume control" (this is on fedora 11, but should be same on fedora 12).
- select Alsa mixer
- go to switches tab
- select headphones (I suppose "Speaker" is already sellected)

It works for me using vlc, skype, audacity, flash in firefox, etc ...
NB: my Skype is set to use pulseaudio, so should apply to your problem too

will test again this weekend

Seems I had those settings already - but I have not had a chance to test again just to be sure. I'll post a reply next week.

Got it working!

I finally had a chance this past weekend to want to play with the external jack.

Turns out, I have a myriad of choices for audio output using pulseaudio on this T61P. There are 5 profiles defined: Analog stereo input/Analog stereo output / Digital stereo duplex (IEC958) / Digital stereo (IEC958) output + analog stereo input / analog stereo duplex.

I have almost always opted for one of the digital output profiles - digital is better, right? BUT, if I choose the Analog Stereo output profile, the 'output' tab in the sound preferences dialog adds a new 'connector' options list (that is not present in the digital profiles). Once I select analog stereo, I have the option of output to 'analog headphones' - that is, the output jack on the side of the laptop, enabling me to now hook up to headphones / amps / whatever.

That and some fumbling to get the audio working in my WinXP VM so we could watch a netflix movie, and we were in business!

Thanks for the input. This forum rocks.
