 Posted: Sun Jan 17, 2016 8:31 am Post subject: Sound card lost after installing new graphics card |
 |
|
I have an SB Audigy (emu10k1) soundcard in a machine which also has an integrated Intel HD audio, and a USB camera attached. The Audigy is my main sound card, but occasionally I would use one of others for some specific task. This setup has been working for many years with the snd_emu10k1 being set in /etc/modprobe.d at slot 0 with index 0, the snd_hda_intel at slot 1 index 1, and the usb driver somehow magically appearing at slot 2, no conflicts, everyone happy.
| Code: | excerpts from /etc/modprobe.d/alsa.conf:
...
alias snd-card-0 snd-emu10k1
alias sound-slot-0 snd-emu10k1
options snd-emu10k1 index=0
...
alias snd-card-1 snd-hda-intel
alias sound-slot-1 snd-hda-intel
options snd-hda-intel index=1

Yesterday my old graphics card went to the silicon heaven so I installed an NVidia GTX 750. Since then my Audigy won't load.
| Code: | thor etc # dmesg|grep snd

It turns out slot 0 is occupied by the NVidia card (I presume this has to do with the HDMI port which was absent on the old card)
| Code: | thor etc # cat /proc/asound/cards
0 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xfe87c000 irq 17
1 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xfcff8000 irq 33
2 [Camera ]: USB-Audio - USB 2.0 Camera

Googling around seems to suggest two possible problems which I don't know how to solve:
A) I should correctly assign the slots/indexes
- I don't know how to do this since both the motherboard and the nvidia soundcards use snd_hda_intel which is already assigned to slot 1
B) I might have an IRQ conflict
- if this were the case I couldn't find any information on how to actually solve it
I can workaround this by disabling the motherboard soundcard in BIOS - the NVidia is then assigned slot 1 and my Audigy loads correctly. But I would like to have the onboard card enabled (I use its mic input for skype and occasionally I would route all VoIP through it when the audigy is hooked to jackd)

I have Nvidia Nforce controller and Nvidia GeForce VGA card with hdmi output. After installing card i just change output device in mate-volume-control that's all...
