#148 Version 1.3.0 interfering with PCM DACs

[Dennis Han]

With version 1.3.0, playing PCM files with PCM DACs creates an error message in foobar2000 1.6.4 that the DAC doesn't support the sampling rate (3 out of 3 DACs produce this error). For 16/24/44.1 files, foobar2000 thinks these are sampled at 176.4 kHz, for 16/24/48 and 24/96 the rate becomes 192 kHz. The DSD DAC does play the PCM-to-DSD conversions correctly. Version 1.2.7 works normally.

This looks like PCM gets converted to DoP... Please check that "DSD Processor" is set to "None" on Preferences->Tools->SACD panel.

[Dennis Han]

I had tried that already and there was no change in behavior for playing PCM files with PCM DACs.

[Maxim V.Anisiutkin]

Ok, then foobar console output is needed. Could you, please, check "Trace" in Preferences->Tools->SACD panel and see what's in View->Console? Thank you!

[Dennis Han]

Sorry, I was mistaken. With DSD Processor set to none, the PCM files play through a PCM DAC. The files also play with the DSD Processor enabled at the SACD screen, but disabled at the DSD Processor screen. I sent the log files anyway...

With DSD Processor enabled:

When DSD Processor is active it converts 44100 PCM to DSD64 (DoP64, 176400 sample rate) and it's not playable on PCM DAC (as we see from the console output). Please, try to press "Reset page" on Preferences->Tools->DSD Processor panel and check "Use DSD Processor". DSD Processor will be active, but won't convert to DSD for any sample rate. PCM DAC should work.
