My laptop is offline for the moment, but here's a snapshot of my desktop system. It is an Intel DP965LT, Sigmatel 9227. http://pastebin.ca/897464 You can generate a report like this with http://hg.alsa-project.org/alsa/raw-file/tip/alsa-info.sh. You can also map out your sound chip's connections with http://helllabs.org/codecgraph/ . Mine is attached. -- Tobin Davis Life is a game of bridge -- and you've just been finessed.
