What errors? Is anything actually not working? The way you phrased this reads like it wakes up and works correctly just that you see some errors "somewhere". Read https://bbs.archlinux.org/viewtopic.php?id=57855 and http://www.catb.org/~esr/faqs/smart-questions.html and post something that can be used to even attempt to help you with the problem.

Errors: not start playing video in firefox until reconnect card, loss of samples, jack cannot open PCM device alsa_pcm.

The sound card goes out after 9 seconds of idle time
