We have already support ad1980 driver for 2 years after it is obsolete. Nothing can be supported for ever after it goes EOL. >>>second, ac97 should be just a transport layer, so is there >any reason >>>people cant hook up other codecs via it ? >> >> We have already made the decision to stop supporting >obsolette ad1980 and AC97 in kernel since 2009R1.
