hi. i'm back again with a little issue.
the sound max volume is not as high as the other OS standard.
i had a little thread in the Dell Linux mailing list about this issue:
http://lists.us.dell.com/pipermail/linux-desktops/2008-August/001808.html
and, to make a long story short, Dell's Mario Limonciello told me that the max master volume has been reduced from 0xff to 0xec, to solve some distortion (resonance) issues at higher levels, with this commit:
http://git.alsa-project.org/?p=alsa-kernel.git;a=commit;h=d654a660355f9dc30d...
this is not going to change until there's some Band EQualization software support in the alsa driver that can reduce this resonance issues at higher volume levels.
do you know if something like this is in development?
i gave a quick look to the Stac/IDT 92HD73C1XXX codec datasheet http://www.idt.com/?genID=92HD73C1 and i'm going to believe there's no HW support about band filtering.. (the datasheet indeed speaks about a SigmaTel Kernel Processing Interface AKA /SKPI/ ) so it should it be a complete software solution for linux too! right?
