reflum, PCM does not contain any header. This means you need to ensure yourself that both, mpg321's and ices2's settings match.
In case your audio is really mono and ices2 thinks it is stereo it will read each even sample as right channel and each odd sample as left. this will make it sound like it would play twice as fast (including everything moved one octave higher). Does mpg321 has some info on what it will output exactly? if so please ensure ices2's settings match this exactly. Hope I was of help. -- Philipp. (Rah of PH2)
