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) >How-To-Repeat: Install FreeBSD-9.1 with GENERIC kernel, use a "Creative SB PCI512". Try to use sound with different applications at Xorg. >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. >Release-Note: >Audit-Trail: >Unformatted:
