[soundnua]: segfaults when selecting bluetooth input device

[Alexander Sack]

TESTCASE: try to select a bluetooth device as input source

10:23 < asac> cyphermox: Program received signal SIGSEGV, Segmentation fault.
10:23 < asac> 0x01492b92 in gvc_mixer_control_change_input (control=0x80115300, input=0x80380b50) at
              gvc-mixer-control.c:736
10:23 < asac> 736I if (g_strcmp0 (active_port->port, input_port) != 0){
10:23 < asac> cyphermox: i guess that has something to do with:
http://launchpadlibrarian.net/103280614/gnome-control-center_1%3A3.4.1-0ubuntu1_1%3A3.4.1-0ubuntu2.diff.gz ?
10:26 < asac> cyphermox: maybe the assumption that is_output is equiv to !IS_MIXER_SOURCE is not correct?
10:26 < asac> active_port = 0x0 btw
10:28 < asac> cyphermox: i man ... i can switch to all inputs, but the bluetooth one ... maybe thats
              !GVC_IS_MIXER_SOURCE :)?
10:28 < asac> i mean
10:28 < asac> anyway ... thanks for checking :)

seems similar to bug #981963

[David Henningsson (diwic)]

This makes the input side look like the output side, so I think it's the correct solution, but you might want to double-check with cjcurran.

[Sebastien Bacher (seb128)]

Thanks David, I commited that patch to both precise and quantal vcs-es and will upload a bit later today

Hello Alexander, or anyone else affected,

Accepted into precise-proposed. The package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

[Andreas Hasenack (ahasenack)]

Works for me, using 1:3.4.2-0ubuntu0.2 from precise-proposed. No longer crashes when selecting the bluetooth headset as input, and the sound works for both playback and recording.

[Marvin Kuurstra (marvin-kuurstra)]

Installed gnome-control-center-data & gnome-control-center-data from precise-proposed and everything seems to be in order.
