 |

I've read nearly every post on this forum looking for the answer I need, but I can't find it...
So, here's the situation:
I have Asus a7n8x DX mobo. Planning on using the onboard nvidia sound. Compiled ALSA into my 2.6.7 kernel. Everything seems good. I emerged the alsa-utils and everything. Unmuted with alsamixer, also double checked with gnome-alsamixer. So, I go to test out my sound with an mp3 through XMMS (configured to use ALSA plugin).
Something odd happens. It will play a fraction of the first second of the mp3, then repeat that about 7 times, then stop attempting playback. So, I jump out of X, and try to do mpg123 to see what that might do. ALSA complains about a device or resource being busy.
Basically, everything I want is going except for sound. Any help offered would be greatly appreciated |

Which kernerl are you using?
I have an Asus a7n8x-x motherboard and alsa worked fine for 2.6.7-rc3-mm2, but didn't work 100% in 2.6.7-mm2. |

| Have you emerge alsa-oss (and maybe also alsa-driver...) ? Have you tried mpg123 twice (sometimes oss players don't work the 1st time) ? |

Strange.
Some lines in /proc/pci:
| Code: | Bus 0, device 5, function 0:
Multimedia audio controller: nVidia Corporation nForce MultiMedia audio [Via VT82C686B] (rev 162).
IRQ 5.

cylgalad: Of course "emerge alsa-drivers" is not necessary for a 2.6-kernel...
Oh, and my /etc/modules.d/alsa:
| Code: | # ALSA portion
alias char-major-116 snd
# OSS/Free portion
alias char-major-14 soundcore
##
## IMPORTANT:
## You need to customise this section for your specific sound card(s)
## and then run `update-modules' command.
## Read alsa-driver's INSTALL file in /usr/share/doc for more info.
##
## ALSA portion
alias snd-card-0 snd-intel8x0
## alias snd-card-1 snd-ens1371
## OSS/Free portion
alias sound-slot-0 snd-card-0
## alias sound-slot-1 snd-card-1
##
# OSS/Free portion - card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
## OSS/Free portion - card #2
## alias sound-service-1-0 snd-mixer-oss
## alias sound-service-1-3 snd-pcm-oss
## alias sound-service-1-12 snd-pcm-oss
alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss
# Set this to the correct number of cards.
options snd cards_limit=1

I can use the OSS-interface or ALSA, the same things happen...
Any ideas?
Thank you... 
Carsten
EDIT: I discovered something just now:
A bit of dmesg:
| Code: | ehci_hcd 0000:00:02.2: irq 11, pci mem e0820000
irq 11: nobody cared!
Disabling IRQ #11 |
/proc/pci and /dev/asound/cards:
| Code: |
0 [nForce2 ]: NFORCE - NVidia nForce2
NVidia nForce2 at 0xed080000, irq 11 |
told me, that the AC97 controller is at irq 11. It's just a thought and im a noob....[/code] |

Ahm, I looked for this "nobody care" problem... And found it:
https://forums.gentoo.org/viewtopic.php?t=188410
I recompile my kernel without ehci now and look, if it works then. thread-creater: look if ehci disables a irq... The irq could be used by the AC97 controller, too. In the thread they say, that it isnt possible to access any other devices on the irq if it is disabled... Perhaps I can do the kernel recompile today (GMT+1)..
Carsten
EDIT: YES! Thats it. My problem is currently solved: I didnt compile ehci. I think I wait for the next release... in the mm release it should already be fixed. |
