First, my apologies - I sent my last missive to Conrad, and not to the list. I'm replying to myself with an update. Details below.

It's just that it's very soft, and I can't get it any louder, though using the slider control in gnome will silence it. This is a recent Thinkpad T61, and grepping dmesg reveals that the sound system is detected as an Intel 82801H, and the codec used seems to be the Analog Devices AD1984. I'm running 7-STABLE, updated on Saturday. Thoughts on how to improve this would be much appreciated. Kurt
