now managed to play a wav through alsaplayer  (alsa output driver).

With the internal card (Intel hd_audio) resume IS working.
With the external usb card (ua-25) resume does NOT work.

no resume from hibernate-ram (playback stops, alsaplayer must be
restarted) with:
$ alsaplayer -r -oalsa -d default:CARD=UA25 ultra_test4.wav

successfull (playback continues) resume from hibernate-ram with:
$ alsaplayer -r -oalsa -d default:CARD=Intel ultra_test4.wav

The usb-card is powered off on hibernation.
A presumption: Maybe it doesn't get enougth time to re-power on.
