This essentially duplicates bug #56781 and bug #60418 as those are not beta-only. The problem mentioned at the end of bug #56781 is still present: When artsd starts first, a message is shown that /dev/dsp cannot be opened (sound module loading too slow?) The audio controller reported is Intel Corp. 82820 820 (Camino 2) Chipset AC'97 Audio Controller (rev 2)
