Comment(by yarikoptic):

 I RESOLVED IT -- details follow:

 ok -- attached things (although i thought browsing through dirrectories
 and diffing would be more 'interesting')

 Mainly I tested audio with calling my cell phone and checking if I have a
 ring tone -- after resume -- no ring tone. Then I accept the call and
 listen if I can hear anything -- and nothing...

 also -- with mplayer:
 prior to suspend
 mplayer -ao alsa /opt/./Qtopia/etc/SystemRingTones/phonering.wav

 plays ringtone fine and exits

 after suspend (apm -s) (Actually after resume ;-) ): it doesn't play and
 doesn't exit, looping in

 nanosleep({0, 10000000}, NULL)          = 0
 ioctl(6, 0xc0844123, 0x83de18)          = 0
 ioctl(6, 0xc0844123, 0x83de18)          = 0
 ioctl(6, 0xc0844123, 0x83de18)          = 0

 where

 1644  open("/dev/snd/pcmC0D0p", O_RDWR|O_NONBLOCK|O_APPEND) = 6

 root at om-gta02:~# fuser /dev/snd/pcmC0D0p
 1382 1387
 root at om-gta02:~# ps auxw | grep 138[27]
 root      1382  0.1  2.6  31772  3248 ?        SLl  17:13   0:01
 root      1387  0.1  1.5  17448  1952 ?        SLl  17:13   0:01

 WTF?

 root at om-gta02:/proc/1382# ls -l /proc/138[27]/exe
 lrwxrwxrwx    1 root     root            0 Aug 19 17:14 /proc/1382/exe ->
 /usr/lib/speech-dispatcher-modules/sd_espeak
 lrwxrwxrwx    1 root     root            0 Aug 19 17:14 /proc/1387/exe ->
 /usr/lib/speech-dispatcher-modules/sd_flite

 HO HO -- could it be silly gpsdrive issue? ;-)

 opkg remove navit speech-dispatcher

 mplayer.... WORKS!!!!!

 doing suspend again (apm -s)
 mplayer works...
 set suspend in configuration and let is suspend
 so please free to reassign this to anywhere you like ;-)
