This is a multipart MIME message. --==_Exmh_-18610525230 Content-Type: text/plain; charset=us-ascii Fred The via82c686.c code changed this week to implement the cold reset described in the AC97 r2.3 spec since there are some boards where the former initialization does not work. It may be your board is reporting it's ready, but it requires a reset. Can you apply the attached patch to the head version of via82c686.c and let me know if it works on your h/w and what the additional dmesg information is? The patch forces a cold reset and sets an additional "enabled" bit in the AC97 link control register during the reset (there's not enough info in the spec to know whether this bit should be set during the reset, it works elsewhere). Thanks - Orion --==_Exmh_-18610525230--
