I'm running 5.1-CURRENT from about a month ago on my notebook right now,
and it sounds like I have almost identical hardware (Dell C600, etc).
paprika:/boot> dmesg | grep -i pcm
Preloaded elf module "/boot/kernel/snd_pcm.ko" at 0xc0aa8280.
pcm0: <ESS Technology Maestro3> port 0xd800-0xd8ff mem
0xf3ffe000-0xf3ffffff irq 5 at device 8.0 on pci0
pcm0: <SigmaTel STAC9721/23 AC97 Codec>
Preloaded elf module "/boot/kernel/snd_pcm.ko" at 0xc0aa8280.
pcm0: <ESS Technology Maestro3> port 0xd800-0xd8ff mem
0xf3ffe000-0xf3ffffff irq 5 at device 8.0 on pci0
pcm0: <SigmaTel STAC9721/23 AC97 Codec>
I have the following in my loader.conf:
paprika:/boot> grep -i maes /boot/loader.conf
snd_maestro3_load="YES"
I'm about to update to 5.2-BETA on the notebook; I'm running 5.1-CURRENT
with some modifications to ACPI to make it like my configuration better
(the old Dell notebook patch that's floating around). I don't believe
that patch applies in the new world order, so once I update my notebook
tomorrow, I'll see if I have the same problem. It looks like most of that
patch has been applied to the vendor ACPI code, so I'm hopeful it won't
:-). You might try disabling ACPI in device.hints and see if your sound
device "magically appears".
