HDMI Audio and Flash

[4dplane]

After spending a day on this topic I found that this works inside of ~/.asoundrc

pcm.dmixer {
type dmix
ipc_key 1024
ipc_key_add_uid false
ipc_perm 0660
slave {
pcm "hw:0,3"
rate 48000
channels 2
period_time 0
period_size 1024
buffer_time 0
buffer_size 4096
}
}

pcm.!default {
type plug
slave.pcm "dmixer"
}

I have two audio cards so pcm "hw:0,3" is not my HDMI so I had to change it to pcm "hw:1,3" and it works!

Also, all I have to do is change pcm "hw:1,3" back to pcm "hw:0,0" and all audio goes out the 1/8 inch jack instead.

Hope this was helpful

Thank you very much Johan. Your information is very helpful!

Sorry I can not help you with the problems
Only a few comments:

OverScan: Are not the settings stored in /etc/X11/xorg.conf? In your first post you said you were using HDMI for both audio and video, but in the last one you mention using DVI for LCD monitors. Do you have the overscan problem with both connections?

Gnome sound (Is this what you mean by 'ubuntu buttons'?): Usually it goes through esd (Enlightened Sound Daemon).

Thank you again and good luck!

The Nvidia's overscan problem is only found on HDMI and S-video.
Nvidia goes even further by ignoring the xorg.conf. So many options are not possible like
"Mode" for instance.
With this option it would be possible to find a workaround for the overscanning.

The sound I meant was the sound of clicking buttons etc. I'll google my way with "esd", thanks for that.

I managed to find the fix a couple of days ago.

Edit or create .asoundrc.

sudo gedit ~/.asoundrc

Add the line

defaults.pcm.device 3

Reboot.

Hello,

First at all, I'm sorry for my bad english.

I have a problem with this solution, if I put this option on my .asoundrc, flash works fine, even gnome sounds effects (like push buttons ..), but xbmc doesn't work. If I don't put this option on my .asoundrc, xbmc works fine but others options don't work.

How can I select what device I have to use for 'each application'?

Maybe, it's easier to put the option that you explain before and later, fix xbmc. I have followed an "howto" http://www.xbmc.org/forum/showthread.php?t=53812 to install xbmc and I don't know how to setup this for another option.

Thanks in advance,

Carlos

Hello,

Ten minutes later from my last post, I have fixed my own question. In sound options of xbmc, in output option I have changed 'hdmi' for 'default' and it works fine (I have had good luck)

Thanks

Carlos.

Great Post Plaguester!

I added the file you suggested and I now get sound via HDMI from my Nvidia 9300 to my Samsung 550 HD TV.

Before that I added the alsamixergui and then checked off all the IEC958 tick boxes. - had sound at that point but not for everything - and no sound with flash - now it all seems to work ( tested on hulu)

This worked for me thanks a lot.

i know this is an old thread but i have the same issue just with karmic. .asoundrc doesnt exist and i was wondering if there is a fix for 9.10?

[Plaguester]

9.10 shouldn't need the hacky fix. Just go to System > Preferences > Sound, goto the hardware tab, and choose HDMI out for the hardware profile.

This worked great to get Flash running over HDMI for me. My system has onboard analog audio with an add-in ATI video with HDMI out. Before this fix, I could switch sound back and forth through the System -> Preferences -> Sound menu but could not get Flash audio through the HDMI. The one downside to this fix is that it forces all audio over HDMI. I can't, even manually using the menu above, get the sound to switch back to the analog without renaming the .asoundrc file and rebooting. Is there any way to not 'hardset' the audio device in .asoundrc and have it look at the Sound menu settings. I'd like it best if the system could send sound over both devices but I'd settle for not having to reboot. Thanks and great work-around.
