Hi.
Help me configure HDMI Sound on Acer N282.
No sound HDMI.
ALSA information is located at http://www.alsa-project.org/db/?f=6bb8867852c060031e42170adf68178ae7dc4fca
That alsa-info report says you are running 11.4 Milestone 6, so you should have posted your help request in the Pre-release/Beta forum as it is a pre-release version of openSUSE. 
I see this is your first post, so welcome to the forums. 
Hi
would you post a bit more information? Please post few more details about your machine…would you post the output of lspci and aplay -l ?
I googled “ACER N282” but was unable to find the complete specs…I think this is an atom machine? probably integrated everything?
And please post the command output, as requested by @pimanac, pasted and wrapped in Code tags (Go Advanced, highlight the pasted output, click on the “#” icon).
If the HDMI cable is comming from your video card, then the nVIDIA video sound is not the default, but Intel.
!Soundcards recognised by ALSA
!!-----------------------------
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xfe9fc000 irq 44
1 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xfcf7c000 irq 17
Not sure if this supports all sound types, but you can go into YaST / Hardware / Sound and select the “HDA-Intel - HDA NVidia” then pick the “Other” button on the bottom right corner and select “Set as the Primary Card” for the nVIDIA and see what that does.
Thank You,
Acer Veriton N282, Atom 2CPU, GT218 ION

Hi sahorov-se,
I am not a moderator in this forum, but if you have a problem, don’t post it twice, even if it’s not at the right place. A moderator will move it if necessary.
I respond to the same problem you posted here : No HDMI sound on (Acer Veritone N282)
Hope it helps.
And that’s not posted using CODE tags as requested above. For next time, I suggest you read: Posting in Code Tags - A Guide as requested by Moderators (not me). Helpers can then see it exactly as it comes from the terminal, as they are used to seeing it, even though your formatting looks nice. 
From a terminal, issue the command alsamixer Make sure nothing in here is muted. Press F6 to switch between cards and exit when done.
your Nvidia Device is card #1 (see your aplay -l above) but it has multiple “devices”. Ive had this problem for quite some time on linux with audio over hdmi. Sometimes they sound system gets confused between all the different devices.

We are going to see if any of these devices are working by using speaker test. You can press CTRL-C during any one of these tests to stop. If you get the error “no device found” you can go ahead and press control-c
speaker-test -Dplughw:1,3 -c2
speaker-test -Dplughw:1,7 -c2
speaker-test -Dplughw:1,8 -c2
speaker-test -Dplughw:1,9 -c2
if one of these works, you will hear white noise out of your speakers, once on the left channel and once on the right channel. Id be willing to bet its either device 3 or 7. But try them all nevertheless.
Let us know the results!
Has anyone found a solution yet?
I have exactly the same problem.
Sound via analog output works,
Video with nvidia driver via HDMI works,
no sound via HDMI.
I am using the released OpenSuSE 11.4.
My ALSA Info is at
http://www.alsa-project.org/db/?f=6022590a1a5aaee89e8efa873677312484b30a5f
I tried all the speaker-test calls.
133 speaker-test -Dplughw:0,0 -c2
134 speaker-test -Dplughw:0,1 -c2
135 speaker-test -Dplughw:1,3 -c2
136 speaker-test -Dplughw:1,7 -c2
137 speaker-test -Dplughw:1,8 -c2
138 speaker-test -Dplughw:1,9 -c2
OK, I found the solution.
You have to put
options snd-hda-intel enable_msi=0 probe_mask=0xffff,0xfff2
into /etc/modprobe.d/50-sound.conf
Reboot and the aplay list now is much cleaner:
# **aplay -l**

Also, sound via HDMI now works.
Ahh yes. I remember now having to do this a while back with Mythbuntu…except they call the file /etc/modprobe.d/sound.conf
Glad you got it working! Makes me kick myself in the behind for not writing things like this down on a piece of paper!
Hi all,
I reopen this thread as I feel it looks like my situation. I have a question for the experts : how did cko manage to find his probe_mask ? How do I find mine ? I’d really like to make HDMI work on my computer.
Video work, but no sound at all. Here’s my alsa file :
I forgot :
hwinfo --gfxcard | grep -i -e model -e driver
Model: "nVidia GeForce 9600M GT"
Driver: "nvidia"
Driver Modules: "nvidia"
Driver Info #0:
Driver Info #1:
Oh my god!!!
What a shame… :shame:
It’s been so long that I try to make HDMI sound to work on my system and I just found out that the S/PDIF 1 channel in alsamixer was muted. 
I went a lot of times in alsamixer but never saw that it was muted.
HDMI finally work on my system. rotfl!
