Unable to boot after installing new sound card AE-7

Guess the error message : NMI watchdog detected hard lockup on cpu 21. It’s basically what I was expecting. The only other post i’ve seen on reddit the guy literally had the same issue and no other linux distro worked either :

https://www.reddit.com/r/SoundBlasterOfficial/comments/10kmsv0/problem_with_creative_ae7_any_linux_doesnt_start/

The person ended up trading it’s AE-7 for an AE-5.

Yes here shows working but the motherboard is different hardware so i don’t know.

Indeed. I really don’t know what’s happening. The person seems to be fine on Kernel 6.x… I`m booting EOS on kernel 6.3.1 so it should not occur.

This is also this :

Might be related but they talk about Intel NUCs.

ok so I’ve made some kind of progress here. I was able to boot with the card in. This indeed seems to be a conflict with the snd_hda_intel module and my new card. I blacklisted the module by creating a conf file in /etc/modprobe.d folder named snd_hda_intel.conf and added the following inside :

blacklist snd_hda_intel
blacklist snd_hda_codec_hdmi

So this disable the intel sound mostlikely coming from one of the hdmi port on the video card or onboard. Right now If I do lspci I can see the new soundcard but it’s not available in the audio panel.

67:00.0 Audio device: Creative Labs Device 0010 (rev 01)

I’m not far from success I think.

EDIT: the snd_hda_intel might also manage creative sound card…

Maybe you should name it differently? Maybe it should be blacklist.conf with the two entries inside the file.

I also think then if the card is actually listed you may have to set the priority.

The black listing is working at the moment. I can load EOS but the sound card is not showing in the audio panel and alsa does not see it either. It might be that the snd_hda_intel is also managing creative sound card…

Can you list the cards with aplay -l

The only 2 devices appearing there are my SteelSeries Arctis 7 headphone that I use only when I’m gaming with friends.

What does inxi -Aa show

Basically I answered my own question : snd_hda_intel is used to handle creative soundcard. So If I blacklist it I won’t play audio from my card. So there is a conflict somewhere in the module between the audio from that sound card and something else :

Did you look at this?

Did you use lspci -nnk to try to get the hardware id’s? Not sure if it will show?

67:00.0 Audio device [0403]: Creative Labs Device [1102:0010] (rev 01)
	Subsystem: Creative Labs Device [1102:0081]
	Kernel modules: snd_hda_intel

Are you confident that is the actual sound card in question?

Yes. There is no other Creative lab audio device in the computer. The onboard device which is disabled is a Realtek other than that there is the Nvidia Audio and Ati audio from the display ports and hdmi.

Maybe try in /etc/modprobe.d/alsa-base.conf

add

options snd-hda-intel position_fix=1

Edit: If it doesn’t work just remove it.
