I have just added the second Kingston memory stick to my computer. After connecting everything,I had arranged a chat with my client but my headset microphone is not working. I have tried to change all the slots but to no avail:
I have tried everything, including using alsamixer:
Every time I reboot my comp second column,headphone goes to 0!
What should I try next?
If removing the RAM stick that you just installed fixes it, then that could mean the RAM is bad and you'd have to run memtest86+ http://memtest.org/ or something like that to verify. (This is unlikely, but possible)
If it's still not working after removing the second RAM stick, then you may want to test the microphone on other PCs with the same and different Operating Systems if possible to make sure the mic didn't just happen to die right when you installed your new RAM. (Also unlikely, but also possible)
Hope one of these helps with your issue.
