Description hardy.schumacher 2012-12-30 12:50:00 UTC 
After upgrading from FreeBSD-9.1_p05 to FreeBSD-9.1 the sound card "Creative SB PCI512 [CT4790]" is not working anymore.

With FreeBSD-9.1 the driver "snd_emu10kx" is built in GENERIC kernel by default.
It detects the sound card correctly, but with Xorg no sound is available.

Formerly I used module "snd_emu10k1", which worked well with the named sound card.


Details (based on driver "snd_emu10kx"):

Command: dmesg | grep -i "emu"
Output:
emu10kx0: <Creative SB PCI512 [CT4790]> port 0xe000-0xe01f irq 19 at device 11.0 on pci0
pcm0: <EMU10Kx DSP front PCM interface> on emu10kx0
pcm1: <EMU10Kx DSP rear PCM interface> on emu10kx0

Command: cat /dev/sndstat
Output:
FreeBSD Audio Driver (newpcm: 32bit 2009061500/i386)
Installed devices:
pcm0: <EMU10Kx DSP front PCM interface> (play/rec) default
pcm1: <EMU10Kx DSP rear PCM interface> (play)

Fix: 

A workaround is to use a custom kernel:
include GENERIC
nodevice snd_emu10kx

With this kernel I load the alternative driver "snd_emu10k1" via /boot/loader.conf.
This works well.

Correct solution would be to migrate all functionalities from "snd_emu10k1"
into "snd_emu10kx" that the newer driver is fully backward compatible.
How-To-Repeat: Install FreeBSD-9.1 with GENERIC kernel, use a "Creative SB PCI512".
Try to use sound with different applications at Xorg.
