KeepSoundAwake 1.3 Addresses an OS X PowerBook Audio Problem

KeepSoundAwake sits in the background and plays a “silent sound” every 20 seconds, thereby preventing the audio hardware from sleeping.

This application is only useful if you have a recent PowerBook and OS X 10.1.2 or higher. It will not hurt otherwise, but there’s no point in running it. Due to a design flaw, the OS sleeps the audio hardware if 30 seconds go by without any sounds being made, regardless of whether or not the machine is plugged in. This is annoying, as the audio hardware must be “warmed up” for about 2.5 seconds before the system can beep, and during those 2.5 seconds you have to watch the beachball spin.

On top of this design glitch, there’s a bug (Apple bug #2845648), which occasionally prevents the audio hardware from waking up again. This can hang those applications which attempt to play sound (such as iTunes or the menu-bar volume slider).

KeepSoundAwake does seem to prevent the the sound hardware from sleeping, but it does not address whatever is causing the hardware to go narcoleptic. Sometimes sound still cuts out, and you must plug something into the headphone jack in order to wake it up. Perhaps they’ll fix it for OS X 10.1.3. If you have audio problems, please report them to Apple.

New in this version: Addresses a memory leak that OS X 10.2 Jaguar users found. Thanks for the bug reports!

Apple has put up a knowledge base article acknowledging the problem that this program addresses. Best of all, it has a complete list of the affected hardware.

System requirements:

  • Mac OS X 10.1.2 or higher
  • A Mac model listed in Apple knowledge base article 106766

Folks still running 10.1.x may download an older version from the developer’s site.

KeepSoundAwake is freeware.

IOGear Explains about HomePlug Technology with New User Guide

IOGear has launched a 10-point guide for users who want more information about HomePlug technology.

HomePlug enables consumers to create a home network using existing electrical wires. It allows users to share Internet access, printers, and other devices, as well as transfer files and play games. By connecting a computer through either an ethernet or USB port and plugging the power end into an outlet, users are immediately networked to other home-plugged devices up to 900 feet away.

The guide is in response to customer demand for a quick overview of the emerging technology. The guide covers basic information such as, “What is HomePlug?” and “What are HomePlug’s benefits?” through to more complex questions like “How fast does data transfer over the electrical wires?” and “Are there any security risks associated with data being sent through electrical wires?”

“Home users don’t have access to IT departments like corporate users do, so it’s difficult to get an overview of an emerging technology without investing a lot of time on research,” said Miranda Su, vice president of sales and marketing at IOGear, Inc. “This guide is designed to provide a brief overview of the technology and should answer all of the questions home users wanted to know, but didn’t know who to ask.

IOGear’s HomePlug guide is freely available from the IOGear website. Those who have specific questions can also call the company’s toll free customer service number on 866-9-IOGear.
