Comment 4 for bug 462654

I have an acer aspire 5930g, after a clean install of Karmic 64bit the sound works perfectly except the tuba bass. The problem is that alsa picks the option model=acer-aspire-4930g by default for this laptop, whereas I found that model=acer-aspire-6530g fits much better. With the latter option everything works, including the tuba bass, and all the built-in speakers get muted automatically upon headphones plug-in. Also the sound quality is very good.

From the changelog between alsa 1.0.20 to 1.0.21 (in Karmic backports) we can read: " - ALSA: hda - Use model=acer-aspire-6530g for Acer Aspire 6930 For Acer Aspire 6930G (1025:015e), acre-aspire-6530g model matches obviously better" .

I believe also 5930g should be moved over like 6930g.

The only thing I'm not 100% positive about is the built-in mic, I've had no time to play with settings and volumes yet and for now it seems to only produce noise for me; if I manage to get it to work I definitely write to the alsa developers to suggest the move of the 5930g from 4930g settings to 6530g.
