Thanx

My application uses the low level Qt multimedia, i.e. th soundcard. I do read a stream of samples, do some processing then (filtering, spectrum etc). I have the application using portaudio, which gives problems on Linux (interfacing to alsa). Under windows it works fine.
Recently someone suggested he use of the low level features of Qt multimedia (i.e. audiodevice ...), There are some elementary examples such as
getting a devicelist, which I started with.
Again, under windows (both vista and w7) it works fine, under Linux (fedora 12 both 32 and 64 bits) it seems to be impossible for me) to
run the elementary examples (audiodeviceinfo examples) , since they result in a crash apparantly in alsa (using the latest version).

so, one could say, I am in need of help

best
