The machine is an Armada m700 notebook. Suspend/resume via zzz(8) seems
to work, except that after a suspend/resume, sound is lost.
No error occurs but no sound can be heard. Mixer settings are ok.
Maybe some re-initalization of the hardware after suspend isn't done
by the driver?
The audio hardware is:

esm0: interrupting at irq 11
esm0: ac97: SigmaTel STAC9721/23 codec; 18 bit DAC, 18 bit ADC, SigmaTel 3D
