Title:
[Oneiric] HDMI output does not work immediately
Status in PulseAudio:
Confirmed
Status in pulseaudio package in Ubuntu:
Invalid
Bug description:
In Oneiric, the output of 5.1 sound (not AC3 passthrough, but multi-
channel PCM) via the HDMI connector of my onboard Intel graphics card
is finally working. This is really great!
For this to work, I have configured Pulseaudio to use the "Digital
Surround 5.1 (HDMI) Output". The HDMI output of my computer is
connected to a 5.1 receiver.
However, there is one nuisance: Whenever I start playing sound on the
computer (e.g., rhythmbox or VLC, both playing via PulseAudio), I hear
no sound. On my receiver I have to re-select the input source for the
computer, which seems to initiate a HDMI handshake (it lasts 3
seconds). Only after this I am able to hear sound.
If I press pause and continue in Rhythmbox, the sound continues fine.
If I stop and restart Rhythmbox, I have to do the above procedure
again. The same is true for VLC and probably for all other players.
While playing around, I have noticed that sound is also working after
killing pulseaudio while playing something in Rhythmbox. When the
connection to Pulseaudio is killed, Rhythmbox tries a fallback to
ALSA. As the Pulseaudio daemon was immediately restarted, this will
result in Rhythmbox being connected via the ALSA plugin (before the
connection was direct). It seems that Pulseaudio is doing the
necessary things here, because after this I do hear sound (as long as
Rhythmbox runs). However, this trick does not work for other players
like VLC which don't fall back to ALSA.
Note that while for me this is just a nuisance, it may be a real
blocker for other users. As long as you don't try to fiddle with the
receiver inputs while playing sound on the computer, you hear
absolutely nothing via HDMI. This includes the sounds from the speaker
test dialog of Pulseaudio. I guess a lot of users would give up and
think that HDMI output is broken in Ubuntu.
