Notebook right speaker not working, defect?

[kjo]

Info:
windows 7 hp 32bit
notebook made for vista, but upgrated to win7
realtek high def audio, driver 31-May-11 6.0.1.6383
I tried to install a later driver from realtek homepage. Didn't work.
In "sound" -> "config", audio channels are set to stereo, the only setting available.
If testing the left speaker, test sound can be heard.
If testing the right speaker, test sound can't be heard.
If I plug in stereoheadphones, I can hear both left and right test sound.
Q: Can you determine if the right speaker is defect, and it's not a software or setting error?

Note: I think the right speaker used to make sound, but I'm not sure.

Thanks.

From what you have done it would point to the right speaker. Either the speaker or a connection to the speaker. If it's still in warranty contact the PC Vendor. If not, check with your PC vendor on documentation on how to take it apart so you can check the connections.
