#7786: MythTV 0.22 picks wrong PVR-150 audio input
---------------------------------------------------+------------------------
Reporter: Guy Delamarter <gdlex001@…> | Owner: ijr
Type: defect | Status: new
Priority: major | Milestone: 0.22
Component: MythTV - General | Version: 0.22
Severity: high | Mlocked: 0
---------------------------------------------------+------------------------
PVR-150 is set to input (external) composite input, and for the video this
is clearly set correctly in MythTV: live TV shows video. But there is no
sound.
v4l2-ctl lists three audio inputs for PVR-150. 0 is cable tuner (not used
in my setup), 1 is line in 1 (Composite), and 2 is line in 2 (internal?).
The selected input after MythTV sets it is 2. Using v4l2-ctl to manually
change card audio to input 1 while live TV is playing recovers the sound
to go with video! At this point, exiting and turning live TV on again to
the PVR-150 again provides the opportunity for MythTV backend to reset
card audio to input 2 which as before, provides for silent video.
There doesn't appear to be any way to influence this behavior in
configuration (i.e. mythtvsetup). Only selection available is
to use Composite 1 or Composite 2 (selected composite 1) and that is
clearly correct for video.
From v4l2-ctl it appears that the video input for Composite 1 has index 2.
Perhaps the code error is made under the (incorrect) assumption that the
audio index should be set the same as the video index. Since there are
more video inputs than audio inputs, the correspondence cannot follow in
that way. Only a guess...
This used to work fine under mythtv 0.21. Upgraded to using latest 0.22
from rpmfusion repository.
Note that under this defect, MythTV conspires to make unattended recording
of TV with audio very difficult.
