 Posted: Fri Oct 17, 2014 7:13 pm Post subject: Nvidia Optimus + hdmi sound and asound.conf |
 |
|
I have a intel_hda soundcard, using the following drivers:
| Code: |
lsmod |grep hda
snd_hda_codec_via 19239 1
snd_hda_codec_generic 49601 2 snd_hda_codec_via
snd_hda_intel 28463 0
snd_hda_codec 76005 3 snd_hda_codec_via,snd_hda_codec_generic,snd_hda_intel
snd_hwdep 5916 1 snd_hda_codec
|
And when I set up my system for the first time, even with all the drivers loaded, I couldn't get the sound work by any means, even when I opened alsamixer, it showed the soundcard and all its sliders, but I had no sound output at all.
Then I found online a /etc/asound.conf file and put it on my system:
| Code: |
pcm.!default {
type hw
card 1
}
ctl.!default {
type hw
card 0
}
|
And everything magically worked!
Now I have successfully set up my nvidia gtx 860M with nvidia drivers (without bumblebee/primus) and would like my hdmi sound to work. It even shows up anda my alsamixer as a soundcard, but its missing the sliders and all.
Does anybody know how to set it up? Does it need an entry in asound.conf? Does it work using bumblebee/primus? Thanks in advance. |

Just an update, I can see intel hdmi on alsa list, and I can select it on programs like smplayer, but there is no sound at all:
| Code: |
**** List of PLAYBACK Hardware Devices ****
card 0: HDMI [HDA Intel HDMI], device 3: ID 2807 Digital [ID 2807 Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0

I'd like to be as well of as you, sir, but I cannot even get my TV to register anything when I connect HDMI. Did you have to add a Monitor section to your XOrg config? My config is almost identical to that of the nvidia documentation, and I am currently using the nvidia drivers with the tweak for intel to minimize screen tearing.
