Ralston18 :
Here is an old link that may help:

Also:
I found the Maintenance Manual for the dv6 or at least some version of it - seems to support two mono audio output ports. But I also found an "Entertainment Model" that seemed to have stereo audio ports.
Look at the labels and see if you can find the model number. Or go to HP's website and enter the laptop's serial number if you can obtain the full laptop specifications in that manner.
This link provides some possible adapters:

I think you will need the (1) TRS Female to (2) TS Male adapter. (Tip, Ring Sleeve). What the adapter will do is take the respective Right and Left Speaker mono channels (TS male plugs) and convert them for stereo headset (TRS) use. The headset plug being 3.5mm (1/8") TRS male.
Key is to verify that the laptop ports are mono and that the pinouts (connectivity) and plug genders are as I currently understand them to be.
Google TS, TRS, TRRS for further understanding of the specific connections that must be matched.
Thank you, Ralson18. All of your information has been helpful.
I have seen the type of adaptor that you suggested. I was looking for something similar but with 1/8" rather than 1/4" plugs. I know that I could add additional adaptors to go from 1/4" to 1/8", but my fear was that each additional adaptor adds a little more resistance and impedance mismatch to the line.
Unfortunately, after researching my laptop specs as you suggested, I found that the adapter will not solve the problem.
My laptop is an HP dv6-2300 WH770AV. The specs on the sound ports are not specific. So I experimented with speakers and headphones, using YouTube stereo tests.
As near as I can tell, the sound ports are identical to each other, and are mono (or stereo with such poor separation that they may as well be mono). Both my speakers and my headsets use 1/8" TRS plugs. (Thanks for suggesting that I look up TS, TRS and TRRS. I knew what they were, but not what they were called. And I had assumed that TRS implied stereo, but found out that it could also be mono with a separate ground for a balanced line. I had correctly assumed that there were numerous ways that TRRS would be used -- mics, controls, etc.).
Will an external USB sound card bypass any PC limitations? Which USB sound cards would you recommend? My requirements are as follows:
I want to use the sound for audio RIFE applications (applying specific sound frequency sets directly to parts of the body for healing conditions), and for binaural beat applications (for producing healing states of consciousness).
Ideally, I need a full, fairly flat frequency range as far into the sub-audio as possible. The ability to boost lowest frequencies would be helpful, because they have to vibrate the body through headphone earcups.
(I don't care about surround sound or entertainment applications).
Would an external USB sound card work, and produce full frequency sound and clean stereo separation? Would such a card work just as well with an inexpensive netbook? (I am considering one for portability).
Thanks again for responding so quickly, and and for your thorough help.
