Comment 89 for bug 1040873

as for now i cant get anything more than i had (right channel copied)

ive upgraded alsa to this: oem-audio-hda-daily-dkms - 0.201402051428~ubuntu13.10.1
after upgrade i can choose 4.0 in pulse w/o adding pins to rc.local so it works good
im using ubuntu 13.10 and standard pulseaudio (i didnt upgraded this yet)

ive added this:
[Mapping analog-surround-21]
; device-strings = hw:%f
device-strings = surround21:%f surround40:%f
channel-map = front-left,front-right,lfe,lfe
; single path-output is a workaround for old pulse - next lts should be ok
paths-output = analog-output-speaker
; paths-output = analog-output analog-output-lineout analog-output-speaker analog-output-desktop-speaker
priority = 8
direction = output

to files /usr/share/pulseaudio/alsa-mixer/profile-sets/ default.conf and extra-hdmi.conf
(i can choose 2.1 in pulse so it is ok)

tried both
device-strings = hw:%f
device-strings = surround21:%f surround40:%f
didnt heard any difference between them (still right copied)

and in my /etc/pulse/daemon.conf i dont have anything that could collide - stock config for tests (see attached)

so it is just me or version of pulseaudio really makes that difference here?

btw. pulse dont crash when using single paths-output

would be nice to have your pulseaudio configs and if that wont help i will compile newer pulseaudio (there are really no ppas / debs for newer ones?)
