I've updated to 9.0 recently and noticed that I have no audio with AAC. After some tweaking I've managed to get the sound, but I'm not sure I have the most optimal settings.
Here is what I have:
WeTek Hub with only HDMI output.
Yamaha RX-V757 [old] receiver without HDMI but with SPDIF.
- Dolby Digital/Dolby Digital EX decoder
- DTS/DTS-ES Matrix 6.1, Discrete 6.1, DTS Neo:6, DTS 96/24 decoder
- Dolby Pro Logic/Dolby Pro Logic II/Dolby Pro Logic IIx decoder
In order to convert the interfaces between the WeTek and AVR an external splitter/converter is used - HDMI in / HDMI out + SPDIF out.
HDMI Converter Audio Splitter HDMI to HDMI SPDIF
SPDIF output : support 5.1CH audio including Dolby Digital 5.1CH and DTS 5.1CH(it does NOT support Dolby Digital Plus and PCM 5.1CH and beyond)
Converter has a mode switch with 3 options:
Pass - the SPDIF output audio format depends on the TV EDID.
2.0CH - the SPDIF output audio format is LPCM 2CH /my current setting/
5.1CH - the SPDIF output audio format is 5.1CH (the source audio must be 5.1CH)
Finally, my audio settings in LE:
Audio output device: the only HDMI interface
Number of channels: 3 (my rear speakers are not currently connected, no sound with AAC if set to 2)
Stereo upmix: enabled (otherwise no sound with AAC)
Allow Passthrough: enabled
Passthrough output device: the only HDMI interface
Dolby Digital (AC3) capable receiver: enabled
DTS capable receiver: enabled
Please comment and/or advise.
