[Solved] Unsupported audio in recent versions

[SanderBouwhuis]

Since a couple of versions, some of my movies no longer play correctly. I am getting quite a lot of audio errors when opening them:

MPC-HC could not render some of the pins in the graph, you may not have the needed codecs or filters installed on the system.

The following pin(s) failed to find a connectable filter:

Did something change in MPC-HC? Or do I have a setting which is incorrect? Or are newer movies now starting to use codecs which are not supported by MPC-HC?

[clsid2]

The audio decoding is working fine. The problem is that your audio device is not accepting input of 192 kHz.

Solution is to change the audio renderer to SaneAR. That can automatically resample the audio to a (lower) samplerate that is supported by your audio driver.

You are probably also playing video with a different audio format, given that most formats are just 48 kHz. What details does MediaInfo give?

Ok, I found it in the settings. I turned it on, but it still gives me the same error message:

This is what the mediainfo says:

It looks like you enabled bitstreaming in LAV Audio decoder.

If you want to bitstream, then make sure the correct audio device is set as default in Windows settings (or select the device in MPC-HC settings on your screenshot). Driver updates can sometimes mess up the device order in Windows.

In the properties of the audio device in Windows settings, make sure that apps can take exclusive access, which is required for bitstreaming. (The exclusive mode option of SaneAR is irrelevant, as bitstreaming is always done exclusive.)

[SanderBouwhuis]

Where can I turn off this 'bitstreaming'? I couldn't find it in the settings.

These are my Windows settings:

[clsid2]

MPC-HC options > Internal Filters > Audio Decoder

[SanderBouwhuis]

Ok, I got it to work.

For other people encountering the same issue, I had to turn on the checkbox for the 'Fallback to PCM if Bitstreaming is not supported' option:

[clsid2]

You also need to uncheck those boxes above it. You are not outputting to a receiver.
