Hello all,
I can’t seem to get my sound working on my tv I have my computer hooked up to. I can see the audio playing in the pulse audio volume control window, but I can’t hear anything coming out of my tv. I went into terminal and messed around with alsamixer to make sure it was on. It says 00 on everything but I can’t seem to change anything. The video card is a gtx 970, the video works.
Any ideas?
Open alsamixer in the terminal and make sure that the HDMI output isn’t muted.
I did that. I don’t think it is muted, but how can i tell? s/pdif /1/2/3 are all 00. I can’t change any of the inputs to anything else, or at least I haven’t been able to.
edit: I just looked in the options, using there controls I can’t change any of the inputs.
I can toggle off and on with m, but that is it.
Are you using the nvidia proprietary driver or the opensource driver?
Proprietary. I tried the other and that one didn’t work either.
In the Nvidia Control Panel there should be an option to enable or disable the HDMI Audio, make sure the audio is enabled there.
I see the Nvidea X Server Settings panel. I don’t see any audio options listed anywhere. It’s all display options and tweaks.
It’s in the display options. The driver will automatically disable audio on certain brands and models of TV’s due to video corruption when audio is enabled (Sony. Philips, and Vio have a few such models)
I’m sorry, I have looked through the X Server panel. I can’t seem to find anything that would be relevant and I can’t seem to google anything that would give me an idea of what I should be looking for. Can you give me a more specific idea?
Could you post the output of aplay -L?
Here it is.

Please use code or quote tags !
Is the HDMI output set as default in Systemsettings ?
Sorry!
I don’t think so, C-media is the first one listed. when testing it in Systemsettings I didn’t hear anything. I set it to the default sink in pacmd in terminal.
I just noticed that in Volume Control Output tab, under HDMI it says unplugged, although I know that isn’t the case it is giving video.
How do I use code tags?

So the general problem is that it isn’t detecting that the cable is plugged in. Did you try to disconnect and reconnect the cable ?
Was the cable working before with audio ? (I know that there are a lot of crappy cables out there that break every now and then)
Ah, Thanks.
I did just try to recon it. The cable was working before with audio yesterday, but that was with windows installed.
Anybody have any other ideas?
You checked alsamixer already?
Perhaps the channel is just muted?
You need to start alsamixer with alsamixer -c 0 to avoid it showing the pulseaudio mixer. If it isn’t card 0 then you need to adjust that zero.

I have it set so the sink named 0 is hdmi. is that what you mean? when I type alsamixer -c 0 nothing happens. I can type other numbers, like 1,2 etc but not 0
The weird thing about this is that as far as I can tell, it SHOULD be working. It is unmuted in alsamixer, it says it is producing sound int pulseaudio volume control, and I know it is connected because it is working fine visually.
lol, omg. I just looked in the configuration tab. It profile: it says digital stereo hdmi output unplugged. I cahnged it to digital stereo hdmi 2 output. and now it works! I didn’t play around in the options enough. o the shame.
Sovled.
Thanks for the help mate.
