alsa problems multiple cards intel-nvidia hdmi
 

Hello,

I am desesperated with soundcard and alsa configuration that i think that it freezes my system.
I got a lots of problems with my sound-system and maybe a wrong alsa configuration?

My system is: $ cat /proc/asound/card0/codec#* | grep Codec
Codec: Realtek ALC887

$aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC887 Analog [ALC887 Analog]
Subdevices: 0/1
Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: ALC887 Digital [ALC887 Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1

the bootlog always shows:
hda-intel: IRQ timing workaround is activated for card #1. Suggest a bigger bdl_pos_adj.

and after a minutes ... i got freeze system and log shows a lots of:

I like to disable nvidia-hdmi sound , card 1 ... but i dont know how to do it ..

I've read the following to get a right config but no solutions
http://alsa.opensrc.org/index.php/MultipleCards
https://help.ubuntu.com/community/HdaIntelSoundHowto

My alsa-base.conf is :

$cat /etc/modprobe.d/alsa-base.conf
#options snd slots=snd-hda-intel
#alias snd-card-0 snd-hda-intel
#options snd-hda-intel model=auto probe_mask=1 power_save=10 power_save_controller=N
#options snd-hda-intel model=generic
#options snd-hda-intel index=0 model=auto
#options snd cards_limit=1
#options snd-hda-intel model=3stack-dig
#options snd slots=snd-hda-intel

#options snd slots=snd-hda-intel,snd-hda-codec-nvhdmi

options snd cards_limit=2
options snd slots=snd-hda-intel,snd-hda-intel
#options snd-hda-intel=0,1

#options snd cards_limit=1

options snd-hda-intel index=0 model=auto probe_mask=1
options snd-hda-intel index=0 enable_msi=1

options snd-hda-intel index=1 model=auto probe_mask=2
options snd-hda-intel index=1 enable_msi=1
options snd-hda-intel index=1 single_cmd=1
options snd-hda-intel index=1 bdl_pos_adj=128

questions ....

1) options snd-hda-intel index=0 model=auto how to put alc887 removing "auto"

2) can i use snd-hda-codec-nvhdmi instead of snd-hda-intel

3) how to disable hdmi ? can i do it ?

4) how remove bdl_pos_adj message ?

thnk you
