I have the same configuration as David here: CS4280 in a couple with a CS4297A
AC 97 2.1 codec.
I can state that I have no problem with the sample rate:
when playing mp3s I can set any sample rate, for example - 11KHz or standart
44100 - everything is OK.
But I have a one strange thing when playing mp3s:
During playing, when one track changes another, sometimes,
the new track starts playing with a huge distortion and so on
this goes through several tracks then disappears.
Is it b'cuz of using new codec ?
What do you think.
