Dear Maintainer(s),
I have an HP Pavilion DV6-7009el with this soundcard:

IDT 92HD91BXX

00:1b.0 Audio device: Intel Corporation 7 Series/C210 Series Chipset Family
High Definition Audio Controller (rev 04)
        Subsystem: Hewlett-Packard Company Device 1818
        Flags: bus master, fast devsel, latency 0, IRQ 30
        Memory at d4610000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: <access denied>
        Kernel driver in use: snd_hda_intel

I am forced to continue to use Pulseaudio 4, because newer versions (also the 7
one) have this problem (which I found a nearly working (but annoying) workaround to):

* At boot, no audio
* I have to restart pulseaudio and launch alsamixer, choose the soundcard, max
out the headphone volume and unmute it (It is always muted and at 0%)

and NOW I have audio coming out my main laptop speakers (yes, it seems that
from Pulseaudio 5 the mixer level for main speakers is the headphone one).

Now if I plug headphones then the audio comes out only in the headphones and
not from the main speakers (good), but when I unplug them -> settings reset
(which seems to be good
because if I unplug my headphones I want their channel to mute, *but* this bug
gives me no audio on speakers, afterwards).

And sometimes when an application uses audio, the settings revert to mute and
0% headphone channel level -> no audio (so I have to re-do the drill)
For example VLC does not do this, pidgin sometimes does it and sometimes
freezes itself. QBittorrent playing audio through mpg123 triggers the settings
reset once again.


Kind regards,
Mark

Hi

Does moving streams around with pavucontrol fix anything at this point?


Could you attach a verbose log[1] while showing the problem? Also,
please attach the files generated by the pulseaudio bug script (why
weren't they attached?).


[1] http://wiki.ubuntu.com/PulseAudio/Log

ubuntu wiki link you gave me, which I didn't know)

* No restart of pulseaudio nor tinkering with alsamixer after boot.
* Launch VLC with a video, no audio from speakers
* Launch pavucontrol while the video is playing in VLC.
* If I select 'Headphones (unplugged)' in the output, sound works.
* If I re-select 'Speakers', no audio.
* I leave 'Speakers' selected and plug in the headphones. pavucontrol
switches automatically to 'Headphones (plugged in)' and audio goes in
the headphones.
* I unplug the headphones, pavucontrol switches to 'Speakers', VU meter
continues obviously to go up and down, but no audio from speakers.


After this mail I'll send another one containing the same pulseaudio
verbose log but with Pulseaudio 4 to show a working setup.


Kind regards,
Mark

PS: The logs weren't attached in the first mail because I use mutt
launched from reportbug, and reportbug removes attachments when you
edit the report with a MUA). I'm trying to attach everything manually
now.

And these are the logs with pulseaudio 4.0-6+b1

* Boot
* Launch VLC with a video, audio ok
* Launch pavucontrol
* Plug headphones, audio goes through them
* Unplug headphones, audio goes through speakers.

Everything works with this version of pulseaudio, and upgrading event
to pulseaudio 5 gives the same behaviour explained in the previous
message.

Kind regards,
Mark

Hi Mark,

Could you please ask this question in the upstream mailing list?
AFAICT, this is because at some point the default mappings have
changed, but this is really a problem of the  upstream software as we
don't modify those mappings.

The upstream mailinglist is pulseaudio-discuss@lists.freedesktop.org.
