No audio

[wysiwyg]

Good afternoon everyone!  I recently purchased a new computer and have begun working with TC, however, I'm encountering problems with my audio and video (which has its own post).  My first thought was that alsa was muted so I went into alsamixer to check.  Upon going in there I only have two selectable options:

1) HDA ATI HDMI
2) HD-Audio Generic

The first option only has these two editable options:

S/PDIF
S/PDIF 1

The second option has all the adjustable fields you would expect.  The problem is, I need the audio to go over the HDMI cable (video already has no problems).  Since there is only those two options for the HDMI settings in alsa, my thought is that the drivers for the sound card are causing the problem.  Does anyone have any suggestions on how to get this working?

Thanks,
Dave

So based on the other 'No Video' thread, would this also be a problem with not using a newer kernel?  Or perhaps the version of alsa needs to be upgraded?

Thanks,
Dave

I'm not so sure that's the issue, it's perhaps more a question of configuring alsa properly or, if you don't mind trading bloat for functionality, using pulseaudio

I did a quick 'PA vs Alsa' and it appears that PA still uses a bit of Alsa (kernel driver it appears) in order to work.  It looked like there was about the same number of people for or against either which tells me both systems would be ok to use and more or less relies on a users tastes.  Can you mention anything about PA that would be better than Alsa?

I can say that many years ago I was having some problems with audio when I got another new computer and within a few days of all this happening, the distro came out with a new version of Alsa which resolved the problem (most likely due to updated drivers).  I'm not sure of any other config with Alsa other than alsamixer...  Any thoughts?

Thanks,
Dave

Using pulseaudio and pavucontrol makes it much easier to switch between the available input/ouput options for your hardware and any other audio devices (bluetooth, usb) you might connect.

Of course you can also adjust your alsa configuration via ~/.asoundrc, but this takes more effort.

You might want to google .asoundrc hdmi sound and your hardware to see what might be available.

Thanks Juanito, I'll take a look at this later this afternoon!

As the HDMI mux is created by the video card, this too probably needs a newer kernel.

Thanks for the info curaga, I'll report back once I am able to start compiling a custom kernel.
