Re: Sony Clie sound support question

[Alexander Galkin]

Thank you very much for your response. It is actually first time I got any
useful information on this subject. One important detail, however. We do not
have adpcm data. Instead we have 8 kHz and 16 kHz mono regular Windows PCM
data. Also in your code snippet what are 'type' and 'volume_setting'. I
would be very thankful to you if you send me an example how to play raw PCM
data on Sony Clie.

Thank you in advance.
