AC3 Passthrough not working on 1.0b7
|Reported by:||sapphire_user||Owned by:|
I've done quite a bit of digging so apologies if needed info is missing or if this appears to be a duplicate.
I'm running Sapphire on ATV 2.3
Previously ran Sapphire 1.0b6.5 without problems and AC3 passthrough was working.
Installed update from 1.0b6.5. Update went without a hitch
However once running 1.0b7, files encoded with latest ver. of Handbrake using AppleTV settings played no sound when AC3 Passthrough was enabled. Those files have an AAC track and an AC3 5.1/Passthrough track.
If I turned off AC3 Passthrough in Sapphire settings, I did get downmixed stereo.
However, HD video purchased through iTunes store continued to play 5.1 sound without problem in Sapphire.
When I played same Handbrake created files through NitoTV (Quicktime) they played 5.1 sound correctly.
When I initially upgraded to Sapphire b7 I was also running Perian 1.1.3. I upgraded to 1.1.4 without any luck. Downgraded back to 1.1.3.
On the off chance that meta data import was reading audio codec info incorrectly, I deleted my metadata file and reimported. No change with 5.1 playback.
I downgraded Sapphire to b6.5 and 5.1 now plays correctly.
I did read Ticket #292, however chrislutz appears to be having no issues with AC3 5.1 only DTS. I also read your comments and changeset 1121 regarding breaking Passthrough in Perian 1.1.4 and the subsequent fix, however, my problems continued after downgrading to Perian 1.1.3. AC3 5.1 Passthrough is working fine now in b6.5 even with Perian 1.1.4
I also looked at the console logs as suggested above, however, the only thing found in the tail was my Finder reboots after each troubleshooting step mentioned above.
If changeset 1121 will also fix the AC3 passthrough in addition to DTS passthrough, please feel free to delete this ticket.
Great update in all other respects - nice to see so many enhancements in a single update.
