Sorry for the delay, I was travelling all day.

I did apply your patch (to my old cvs version, still having
problems accessing sourceforge).

It made matters better for mpg321 and worse for alsaplayer.

"mpg321 -o alsa09 --audiodevice hw:0,1" still plays 44Khz sounds
too fast, as expected.

"mpg321 -o alsa09 --audiodevice plughw:0,1" now plays 44Khz sounds
correctly. Excellent!

"alsaplayer -d hw:0,1"  still plays 44Khz sounds too fast, as expected.

"alsaplayer -d plughw:0,1" now issues the following error messages:

And plays the sound file via the analog output.
