Reporter: benny@… | Owner: jyavenard
Type: defect | Status: new
Priority: major | Milestone: unknown
Component: MythTV - Audio Output | Version: Unspecified
Severity: medium | Mlocked: 0
------------------------------------+---------------------------------------
Testing trunk-25198 with MythBuntu weekly builds
(0.24.0~trunk25198-0ubuntu0~mythbuntu1)
- Using MSI Meda Live (http://www.mythtv.org/wiki/MSI_Media_Live) with
MythBuntu 10.04 - weekly builds of MythTV
- Pulse Audio is turned off
- Audio Configuration:
- Device set to: ALSA:iec958
- Speaker configuraation: 5.1
- DTS and Dolby Digital is checked
- The computer is connected directly to a Harmon Kardoon receiver via
Digital Coaxial cable.
- Upmix is on - set to "Fastest"
When looking on DVB channels that transmits only 2 channels, the receiver
detect Dolby Digital audio but, the upmix results in just hearing a lot of
garbage.
DVB channels that transmits more then 2 channels, already 5.1 or something
similar, then everything works OK.
Turning off upmix in configuration results that all DVB channels are
transmited with 2 channel audio. Which make me think that the audio engine
do some kind of downmix for channels with 5.1 audio in this case.
