Latest version of htpc is outputting at sample rates that are unticked in the windows settings. My DAC only supports 44.1 kHz and 48 kHs, so I have all other rates unticked for my spdif output. This has been fine up until now. E.g. a 96 kHz file would be downsampled to 48. But in the latest versi…

Which type of audio interface is selected in the settings of Plex HTPC? (it should be “optical”)

Hi. It makes no difference if I set it to SPDIF or leave it on auto. SPDIF is my only enabled output sound device anyway (and as such, the default playback device). It works fine with 44.1 kHz and 48 kHz sources. It used to work fine with other sample rates, so would have been downsampling to fit …

I didn’t mean the actual (name of the) device but the kind of device. [grafik]

Mine comes up as audio device type. But it’s besides the point unfortunately. If I set audio device to SPDIF I get no sound at all. I have to set audio device to autoselect device. That’s off topic and I think there’s another thread on this. My problem is Plex is outputting at sample rates I’ve exp…

What you are bringing up is really in MPV and their audio drivers. There does appear to be some MPV options to set this such as mpv.io .

If it’s related to MPV what would have changed to stop this working vs previous versions of HTPC? Has the MPV binary Plex is using changed recently?

maybe grab the Plex HTPC.log from the current version and compare it to the log from the previous HTPC when your are demonstrating the issue? you could zip and attach them. I’ll try some 24/96 if I get a minute.

I was wrong about things working on previous versions. Also, when I try to set the audio device as spdif I get a playback error. The log is full of possibly unrelated debug, but fundamentally seems to fail around here (see below). It’s very odd. Why is is trying to load the ac3 decoder when the fil…

Going back to the original problem… When mpv queries the device for supported formats the ones disabled in control panel are not excluded so it goes ahead and uses 96 kHz :roll_eyes: Jul 09, 2022 22:42:33.623 [9020] DEBUG - [MPVEngine/mpv] af: [in] 96000Hz stereo 2ch s32 Jul 09, 2022 22:42:33.623…

Really interesting how your log shows MPV checking a lot of formats. I joined another thread about Optical output failing, and ran my own tests of a film with 5.1 AC3. I didn’t get any sound, and I found that the player was trying to load an ac3 encoder into the chain instead of Direct Playing wha…

@PlexJB Another user named Stevenha made an interesting discovery about MPV trying channels and sample rates. Maybe you can get a chance to test his theory on your files too.
