>Description:

This is HP Compaq 6715s laptop.
The sound card is:

hdac0 at pci0:0:20:2:      class=0x040300 card=0x30c2103c chip=0x43831002 rev=0x00 hdr=0x00
    vendor     = 'Advanced Micro Devices [AMD] nee ATI'
    device     = 'SBx00 Azalia (Intel HDA)'
    class      = multimedia
    subclass   = HDA

I have in the kernel:

device          sound           # Generic sound driver (required)
device          snd_hda         # Intel High Definition Audio

In dmesg:

hdac0: <ATI SB600 HDA Controller> mem 0xc0000000-0xc0003fff irq 16 at device 20.2 on pci0

Before X starts I can get sound via /dev/dsp,
or play CDs with
dd if=/dev/cd0 of=/dev/dspcd bs=2352

HOwever, as soon I start X, e.g. with xdm,
or simply "X -config /root/xorg.conf.new -retro"
I cannot get any sound anymore until a reboot.

On the console I see lots of messages:
