[QUOTE="rogerleifert, post: 795972, member: 91014"] [b]AW: SAF v6.00 (based on LAVF)[/b] [SIZE="5"][B]Strange error in MGEG-Audio[/B][/SIZE] Hi to all, after installing SAF6 a mysterious error (re-)appeared in the audio-rendering of Live-TV or TS-Files. I have SPDIF-out and Audio-passthrough for AC3/DTS enabled. SPDIF goes to both an audio-DAC (for music) and to a soundbeamer (for TV/DVD-watching). With AC3/DTS-sound everything works fine. But with MPEG-audio the sound is muted to very low levels (about -50...-60dB) when in stereo-mode. So my DAC and my soundbeamer both show that there are linear PCM-data coming with 48kHz, but they decode them at a very low sound level. Now when I switch (with Dual-Mono-mode enabled) to only left channel or only right channel or mix both channels to mono the sound appears correctly at full level!!! It's as if the upper 8 bit of the 16 bit PCM-sample are shifted 8 bit to the right in stereo-mode (which in theory would give -48dB muting). When I throw the file at graphstudio and press play it's the same behaviour. TS-files with AC3-audio (which is set as "preferred" in MePo) play OK. TS-files with only MPEG- Audio play ca. -50...60dB muted. This behaviour I've had already sometimes in the past, but only very rarely and it didn't disturb. But now it is with every MPEG-audio. Detailed pictures of the graphstudio pins and configuration, MP-logs and SAF6 logs are attached. Your help would be very appreciated. Kind regards Roger [/QUOTE]
