volume control does not work on Galaxy S2 and pulseaudio misbehaves

[Oliver Grawert]

In the Ubuntu Touch port to the Samsung Galaxy S2 phone pulseaudio misbehaves until
load-module module-udev-detect use_ucm=0
is commented out in /etc/pulse/default.pa

while pulse starts after this modification, volume control is neither possible through the indicator (no UI elements at all) nor via alsamixer or the hardware butoons. Videos play with sound, the camera snap sound works too, but volume can not be controlled.

why do you overwrite pcm. default and ctl.default

what is type android ?

System wide config file (/etc/asound.conf)

#pcm.!default {
# type android
# }

ctl.!default {
        type android
        }

pcm.android {
        type android
        }

ctl.android {
        type android
        }

i dont, thats how it is on teh toumch images by default ... the android type is provided by libandroid-audiosystem-asound2 which talks to the container

[David Henningsson (diwic)]

The question is if this is worth spending time on right now, given that we're trying to get rid of audioflinger, and then all this logic will change anyway.

[David Henningsson (diwic)]

But the first one is probably relatively easy - libandroid-audiosystem-asound2 (or some other package) already changes /etc/pulse/default.pa I believe, so we should probably comment out the "load-module module-udev-detect" line on all images that use audioflinger.

[Oliver Grawert (ogra)]

I agree, pulse had a really hard hit on the system that made it close to unusable with udev-detect in place.

For the further stuff i agree we should wait, since the changes are supposed to land this month anyway ...
