if you use pbbuttonsd and the (fn)+F4/F5 buttons to adjust volume, then
pbbuttonsd adjust both master and speaker volume and thus reactivating
the speaker channel. Locate the line reading mixer channels (or similar)
in /etc/pbbuttonsd.conf and remove the speaker-part to have pbbuttonsd
adjust the master volume only or use alsamixer (or any other mixer for
that matter) to adjust master volume only.

On my machine the bass level was way too high after sleep causing ugly
sound, if this is what you're experiencing the solution I found might
work for you too: I have pbbuttonsd start a small script that - upon
resume - uses aumix to restore sound levels _twice_ with intermediate
and with desired settings to force the levels to be touched no matter
what. With this the bass level is set correctly after resume.

Have you tried oss-emulation or sdl ?

AFAIK the alsa source that comes with 2.6 is pretty much the same
than the source in the alsa-source package testing holds, so
switching to 2.4 for alsa would be pointless. If OSS works better
for you - it's still in 2.6.
