HDMI Audio and the new release 12.23
Does anyone know if the audio over HDMI will be working on the new release?
I have been messing with it for months and have had no luck.
I did have a stable system with a Mythdora 10.21 backend, 2 Mythdora 10.21 frontends, and 1 mythbuntu frontend with working HDMI Audio. The HDMI Audio Frontend was the Zotac Ion ITX Mobo.

I have mentioned this before over the last few months but I will ask it again.
HDMI audio works until Mythdora does it's "firstboot". How can I track down where it is going wonky?
Or should I wait for the new release and see if it clears up?
VDPAU & HDMI AUDIO 12.23
It works fantastic.
Make sure you set the video profile in TV Playback to VDPAU..
Yippie!!!
Are there any Ions with
Are there any Ions with enough horsepower to be FE/BEs with the HD-PVR?
I've got a Zotac ION FE as a BE/FE and a ION BE as a SBE/FE
Both seem to work fine, on the ION FE, I'm able to view live OTA HD tv, while recording another program and streaming a previously recorded OTA show to the slave backend/FE on the ION BE.
Hulu desktop works fine on the ION FE, can't say I love the stream that they send, when in full display mode it seems jerky like they are cutting frames out to minimize bandwidth.
Running two HDHOMERUNS, so far have had all 4 tuners recording and did not see any degradation of quality in the recordings.
Using PIP with two live TV streams does seem to drive large CPU usage and cause some issues.
I have not started on HDMI Audio, but have plans to use that after I upgrade to 12.23.
Check your cpu usage when
Check your cpu usage when running huludesktop. I think you'll find the ION doesn't have the decoding power necessary to run it smoothly, hence the jerkiness. I'm hoping a later update of flash is going to fix this issue. What arch are you runing x86 or x64? What version of flash 10.0 (64) or 10.1 (x86 only).
Will check CPU when I get home
I knew going into it that the ION would probably have an issue with running Flash/Hulu, so not a big deal, the funny thing is that it works ok and the audio is fine, just a little disconcerting to watch when it seems like every other frame is missing.
Running 10.21, upgraded to .22 x86, pretty sure that I'm running 10.0 flash, if any of this changes, I will update.
You can get 10.1 here
You can get 10.1 here http://download.macromedia.com/pub/labs/flashplayer10/flashplayer10_1_p3_linux_022310.tar.gz
The PC versions are supposed to have some hardware layer benefits in it, but I'm not sure about the linux binary. Worth a try.
CPU info
Quick update, checked CPU occupancy this am, just running Hulu desktop, nothing else recording or any jobs running. Since this is an ION 330 based machine it shows 4 CPUs, each was running between 50% and 75%. Did not get a chance to update Flash, I will give that a shot to see if any changes.
Sorry for the Thread hijack, last update.
Updated Flash, changed the refresh on the system monitor to 25ms and looking at the resources screen all 4 CPUs using between 50 to 75% occupancy, with an occasional short jump to 100% on an individual CPU. Never see them all max at the same time and never see any prolonged (>500ms) 100% usage. Looking at the processes (knocked that back to a 1 sec refresh) and it appears that Hulu desktop is taking about 40% CPU.
When I run the screen minimized, the quality is better, when I try full screen, it actually seems worse that Flash 10.
As expected toggling the hardware acceleration had no noticeable effect.
I'm going back to 10.0 and do a better comparison to see if there truly is a noticeable difference, or just a subjective one.
One interesting thing is that when they steam at 700k to 1M to fill the buffer, the video is better, when they play from the buffer and then send bursts of data afterwards, the playback seems choppier.
Just an update. I hope this
Just an update.
I hope this is resolved in the new 12.23 release.
I just downloaded the new Mythbuntu to see if it would work and it did. It installed in under 30 minutes on the Zotac Ion ITX as stated at the top of this thread.
HDMI Audio showed up in aplay -l.
The only thing that was needed was the
pcm.!default {type hw
card 0
device 3
}
added to the asound.conf file.
Also for Music playback
You need to set the Music Settings/General in Myth
change to ALSA:plughw:0,3
This is providing aplay -l shows HDMI on
card 0 and device 3
I really hope all this is a moot point with the new release.
You'll probably need to make
You'll probably need to make similar configuration tweeks in any distro. I don't know if you ever tried to do the same tweaks in 10.21, but I know people had hdmi working.
Yes I have tried for months
Yes I have tried for months to get the tweaks working on 10.21 and .22
I have not found anyone that has successfully gotten it to work with MythDora.
Something goes totally wonky when firstboot runs.
Also I noticed that the mythubuntu install was totally gui based this time around so it appears that the need to do a text install not needed anymore.
Is this the case with the new mythdora?
I guess we will find out soon enough...
Thanks again for all you guys do.
I installed 12.23 beta on an
I installed 12.23 beta on an acer revo last night. Setting alsa:hdmi in mythtv is all I needed to do to get it working. I don't think this will be an issue in 12.23.
That is great news. I am
That is great news.
I am looking forward to the new release. ;-)
