Hello.
I've had a problem with low volume on my laptop and while scratching this itch I found the patch titled "hda-codec - Avoid overload of PCM volume on Cx5045 codec" I reverted this patch and of course got a lot more volume. The description states: "The PCM volume of Cx5045 codec has overload that isn't useful but rather harmful. Add a hack to override the amp info to set the max level 0 dB.". Does anybody know where to find more information on a better default value for the max level setting?
Then maybe this workaround is specific to HP laptops. Could you give the alsa-info.sh output, and a more detailed information of your laptop (vendor, model)? Before working on the source code, one should check the mixer setting at first.
