Hi,
I decided to reinstall 13.10 as a new install again after trying just an
overwrite saving files and folders etc. etc. I came to the conclusion that the
.conf files and probably the libraries were a mess after all this testing and
changing of the files, thus the new install.
The HDMI is working in ALSA and Pulseaudio and works for a short time then
stops as it did the last new install. I quickly ran some tests running
{speaker-test -c 2 -t wav}. By switching between the HDMI and the S/PDIF via
the Sound panel while the receiver was in the HDMI auto mode, (auto mode in
either HDMI or S/PDIF on the receiver will automatically switch to what ever
input is receiving a signal) I was able to see the display on the receiver
changing with either selection.
What I have found was the usual, the HDMI has the audio inverted (Right -
Left) and S/PDIF has the proper mapping (Left - Right). Running a 5.1
surround sound test {speaker-test -c 6 -t wav} yielded the the same inverted
mapping for front Left - Right via the HDMI output and the S/PDIF yielded the
proper mapping.
The only difference with 5.1 is that Front Center is not from the center
speaker but what sounded like a spacial mix to center which was via the Front
Left-Right speakers. As for the Rear speakers, there was no audio out. The
audio is roughly 4-6 dB lower and from the front speakers. As for the Sub,LFE;
there was nothing.
To get these results I had to log out or reboot the system to reset the
HDMI a few times. I have read about this issue in some forums,
restarting or relogging. I have tried XBMC and the stereo or 5.1 audio
plays for a while and then stops. Also pausing, stopping or starting
the video will result in a loss of HDMI audio. Restarting XBMC also
does not recover the audio. The information that was sent via apport-
collect was done just before the HDMI audio quit again.
I have ran some tests here on my receiver to see if it had any issues with my
other equipment when the HDMI audio failed on the computer, all is working fine
via S/PDIF and HDMI on the receiver.
I also placed a second distro on the system now. It is latest Linux Mint
32bit. I ran some audio tests there and all is working fine.
I hope all this information will help you both determine what can be
causing the issue so a fix/patch can be available to the user with this
HDMI issue.
