Skype sound / audio problems on Ubuntu 8.10, with Thinkpad T42p


So recently I upgraded to Ubuntu Intrepid Ibex, which I’ve found to be a real improvement (but that’s another story), and then I installed the newer version of Skype which supports video.

Chat works fine, but I ran into a few problems with voice initially, so left it awhile, but today needed video, so decided to sort it out once and for all.

This is the forum post that helped me, although it wasn’t the exact solution so much as fiddling with things through trial and error that helped:
Sound Problems with Ubuntu 8.04 – Skype Community.

So my solution was:

  1. fiddle with the Ubuntu sound recorder, using the volume control utility open to get the sound mixing right – use an mp3 format to get output right in the sound recorder – to make sure you can record something.
  2. once you have that working, go to Options > Sound devices in Skype, to select the correct sound device to use. I had to trial and error each of the sound devices for Sound In to get it to work (was not the default driver – look for Intel 82801 DB-ICH4 (hw:182801 DBICH4,0) ); set Sound Out and Ringing as pulse which worked fine.
  3. click “apply”
  4. try a call and see what happens; if not, rinse and repeat

et voila, it worked for me….

Hope that helps ;-)

As a biologist, zoologist, entrepreneur and techie, this article makes me think we have a fighting chance… incremental changes increase productivity or output, but they don’t make quantum leaps of progress needed to solve some of the real problems of our time, IMHO. Hopefully Vinod and the work he’s doing will affect some of that…

Making cement without also making carbon dioxide seems impossible; the basic chemistry of the process releases the gas. But maybe that’s not really true, Stanford University scientist Brent Contstantz began thinking last year. Of course, it was only a theory, he told himself, but the market for cement is so large — about $13 billion annually in the United States alone — and the pressure to reduce its effect on the environment so strong that he sent a 12- line email to venture capitalist Vinod Khosla.

“I have an idea for a new sustainable cement,” Contstantz wrote. “I’m sure you are already aware that for every ton of [standard] Portland cement produced, approximately one ton of carbon dioxide is released into the atmosphere. My cement wouldn’t do that; in fact, it would remove a ton of carbon dioxide from the environment for every ton of cement produced.”

Khosla, who knew Contstantz only casually — the two hadn’t been in touch for 20 years — was on vacation. But after a discussion that lasted only an hour, he told the scientist, “I don’t care about the rest of the business plan. You don’t need to estimate costs. You don’t need to do a cash flow. You don’t need to do a presentation. Just hire five people, set up a lab, and go.”

Contstantz was astonished. “What we’re up to,” he warned, “takes balls.”

“Well, you’ve got the money now,” was the response. “Get busy.”
