 |
|
I bought a new creative soundblaster surround 5.1 with USB interface to replace my PCI creative audigy zs2 soundcard. I activated the kernel USB ALSA interface, changed the ALSA_CARDS in /etc/make.conf from "emu10k1" to "usb-audio" and re-emerged all ALSA related packages.
After a reboot the new soundcard is recognized and | Code: | | speaker-test -Dplug:surround51 -c6 -twav |
gives me sound from all 6 speakers, but all gnome apps only use both front speakers.
Has someone an idea how to change this?
Here some system information:
dmesg:
| Code: | Advanced Linux Sound Architecture Driver Version 1.0.14 (Fri Jul 20 09:12:58 2007 UTC).
usbcore: registered new interface driver snd-usb-audio
ALSA device list:
#0: Creative Technology SB Live! 24-bit External at usb-0000:00:02.0-8, full speed |
grep SND .config (only enabled ones)
| Code: | CONFIG_SND=y
CONFIG_SND_TIMER=y
CONFIG_SND_PCM=y
CONFIG_SND_HWDEP=y
CONFIG_SND_RAWMIDI=y
CONFIG_SND_SEQUENCER=y
CONFIG_SND_OSSEMUL=y
CONFIG_SND_MIXER_OSS=y
CONFIG_SND_USB_AUDIO=y |
grep SOUND .config (only enabled ones)
alsamixer shows only one PCM bar, not like with the old card about dozen |

Which version of the udev you are using?

I found this information: http://gentoo-wiki.com/HOWTO_Install_Creative_Sound_Blaster_Live_24-bit_external_(usb)
This sentence is not too good for me: Using the SB Live USB box under gentoo. (Note: no Creative USB card will give you proper surround sound (except when doing HW AC3 decoding). If you want a decent surround USB soundcard, better check out Terratec's Aureon, works flawlessly under Linux.)
But the aureon is only 16Bit, I just wanted a 24 bit soundcard |
