[Alsa-user] kernel: codec_read 0: semaphore is not ready for register 0x2c / Sound

[Wolfgang P. R. <wp....@gm...>]

When booting the computer , sometimes the sound works and sometimes not.
I run FC8 on a Fujitsu Siemens Amilo 1425 Laptop.
I ran Ububtu and sounds works with no problem. Also under Windows
works sound fine. I had this problem under FC6, 7 and now 8.
