Isn't it rather alreadyRead += read; ?

The "alreadyRead" counter is the amount of bytes read.
The read() method reads only one byte and return the value of this byte.
So just +1 at every call.

channel is then apparently not used, is it normal ?

Good catch. I used this on a previous try but it is not needed.
I will remove it.
Allows the use of a Sizeable interface (for AudioStream that we know the length of, but we cannot clone). We can then improve the duration detection, for example for the pulseaudio sink (PR coming after). We can also give the length information to sink in more cases. Add the support of the mark / reset methods to some common AudioStream. We then allow more stream analysis for sink requiring it (Stream analysis often requires to get back in time after consuming a few bytes) Signed-off-by: Gwendal Roulleau <[email protected]>

Add another way of computing sound duration (using information from the AudioFormat class)
