>Description:
pcm sound levels on my Dell GX240 are much lower than expected. i
am using a known good set of speakers that work well on a older
Dell box with identical FreeBSD version. sound is inaudible unless
mixer pcm & ogain are both set above 80%, mixer vol setting makes
no difference. output levels appear identical on the speaker jack
and headphone jack. headphones sound ok at ogain=50, pcm=75-100;
speakers get enough volume for a small quiet room at ogain=95-100,
pcm=75-100 but sound is clipped and distorted (probably due to
nearly maximum settings)
the application used does not seem to matter. i've tested w/ xmms,
mpg123, realplay and a variety of audio formats.
this patch (inspired by kern/66422) made no difference

sound works great on a Dell GX200 (p3, Intel ICH 82801AA) running
the same build of FreeBSD-Current, and plays louder than I can
comfortably listen to if i turn the mixer settings up to similar
levels.
