Summary:                    Power Management is broken following changes from
1.0.10 to 1.0.11.x versions
Description: 
I had linux kernel 2.6.15 on my machine (with alsa version 1.0.10).
I could place my laptop on standby while playing music, and onced resumed
the playback would also continue..... proper functionality and power
management.

following an upgrade to kernel 2.6.16 with latest patches (includes alsa
1.0.11-rc4), the power management does not function correctly.
basically, i have to restart the alsasound service after resume to have
any sound again.

2.6.17-rc4 is too unstable for my system.
the kernels 2.6.15 and 2.6.16 (which i have) are heavily patched to enable
suspend-to-ram and other features working on my system.

if you feel a newer version of alsa is the solution to this problem,
i can try compiling cvs snapshot of alsa-kernel module (from alsa-project
cvs tree) and integrating it with kernel 2.6.16; unless you feel 2.6.16 is
too old for that...

alternatively, if you think my problem is kernel related and the 2.6.17 is
the solution, i'll go after fixing my suspend feature... that'll take some
time, and i don't want to hassle you with kernel bugs/etc....

Umm... you should really have mentioned that your kernel was heavily
patched.  How can we be expected to support such a random configuration?

You really need to get the suspend issues resolved before you conclude
it's an ALSA bug.
