Issue is pretty simple...

I have a JetWay MiniTop PC, model # HBJC600C99-52W-BW. I recently installed xbmc Frodo. It all seems to be OK, except that there is no HDMI audio output.

From what I can tell, analog audio and the spdif work through the onboard "usb audio device". The audio hardware in the nVidia HDMI hardware does not seem to be detected.

Here are my XMBC logs.

ALSA mixer sees two devices, HDA NVidia (default) and USB PnP Sound Device. NVidia shows only a SPDIF connection and it is not muted. The USB device has speaker, Mic and Auto Gain Control.

Can I get some help as to how to get HDMI audio output working on this machine, please?

Edit: Adding a few more details...

I've tried updating as shown in this post.

screenshot of audio settings in xbmc please. (hint, press prtscr on keyboard)

debug log (wiki)

All the settings don't fit on one full screen. It also doesn't make a difference which I select. I will grab the screen shots and upload them when I get back home tomorrow morning.

From what I remember, the three settings I think are important on the audio screen have the following choices:

Audio output: HDMI / Analog / SPDIF
Audio output device: Analog / SPDIF
Passthrough output device: SPDIF

I can SSH to the XBMC machine now if there are any files or settings that I can see from a command prompt. Otherwise I have to wait until tomorrow to get more info.

One item to note... This is booting from an SSD and I am reading online that XBMC can start too quickly - before the audio hardware is initialized. I am seeing the following message at the end of the dmesg log:

[ 12.204488] input: HDA NVidia HDMI/DP,pcm=3 as /devices/pci0000:00/0000:00:1c.0/0000:01:00.1/sound/card0/input5

Could 12 seconds(?) be too late for XBMC to see and utilize the NVidia audio hardware?

Ahh OK well that explains it. There is a hack to change your autologin to wait a while which fixes this. I'll be right back when I find the link.

Thanks!

I've updated the file but won't be able to test until tomorrow.

xbmc was changed to wait at least for "one" audio device. If nothing helps, blacklist your analog stuff :-)

frodo or post frodo?

post.

I think many people don't want to go beyond stable, so the lightdm fix is still relevant to many people.

I think your right, but I dont agree "stable" is actually best and these many people, are only basing their decision on information available.

Considering the maturity of AE I would say it has long way to go and the more ppl testing and working with current fixes the better chances bugs are fixed if these things are reported in first place.

Thank you very much. That fixed my issue.

I now see the NVidia hardware in the output device and passthrough device.

Sorry for piggybacking on your post OP, I have the exact same box but I'm struggling with a similar problem.

In my case I'm not using the HDMI audio rather the analog output labelled, "USB PnP Sound Device"


Sporadically while coming out of resume, the "USB PnP Sound Device" device is no longer in Audio output device (System->Audio Ouput). Instead I see, "Playback/recording through the PulseAudio sound server" and I get no audio.

I'm on xbmcbuntu 12.2,
"Linux jetway 3.5.0-42-generic #65-Ubuntu SMP Tue Oct 1 21:38:59 UTC 2013 i686 i686 i686 GNU/Linux"

Please help, as I need to use the analog output.

I tried to alter the /etc/init/lightdm.conf as per above post, same...

Your lightdm.conf won't help coming back from resume. It only governs initial login.
