The sound driver works perfectly, by and large, BUT, the analog loopback has been left active, which results in a massive feedback problem as the (EXTREMELY) sensitive built-in mic picks up the soft hiss of the speakers, and, sent through the loopback, amplifies it to an ear-piercing level. This is incredibly easy to fix. First, plug a set of headphones into the audio jack in the front of your 1525 Inspiron. This will prevent severe hearing damage and/or cardiac arrest. =P Once Mandriva has started, right-click your volume control (KMix), and select Show Mixer Window. Now, I've heard others recommend disabling the Capture device in Inputs. However, this means you can't record from the mic any more. The better solution is simply to disable the loopback, which feeds the speaker back into the mic in a loop that results in the squeal. So, in the mixer, select Switches (rather than Inputs), and mute the Analog Loopback. Done. Now, no more squeal, and everything else in the laptop works 100 percent, including wifi. Plus, you can still record through the mic. :) Chris. http://www.linux-disks.com Mandriva Spring 2008.1 will install with only one hitch - a massive squeal when you start the system for the first time after installation.
