Issues USB DAC

(1/4) > >>

streamerguy:
Hi,

Last week I bought a Raspberry Pi 4 (also have this issues with an older RPI3B) to have JRiver for linux installed and use it to connect to a USB Dac (Marantz NA11S1).
Everything seems ok, but I have issues when I create a playlist with tracks and different sample rates. Apparently it takes some time for the Dac to switch to the new sample rate, thus resulting in stopping. Weird thing is thsi happens not always. When I skip manually in the playlist to a track with a different sample rate, it almost always goes wrong, but when I click again on the same track it plays fine.
I suspect it's got something to do with timing.
I am using the hw,dev0 device without puleseaudio and I played a lot with "prebuffering" and "Play silence at startup for synchronization" settings.

Of course i can resample everything to the same sample rate, but this is not bitperfect anymore.

Hopefully someone can point me in the right direction.

Best

This output format may not be supported by your hardware.  You can use DSP Studio to change the output to a compatible format.

Also, make sure that your system has a valid sound playback device and that it is properly configured in playback options. callba

I did some more testing and changed all sample rates in DSP studio to the same sample rate, but even then the skipping issue exists.
It seems that the problem is only there when I change a track manually, if I create a playlist with random sample rate order and let it run, tracks are not skipped.

I also noticed that when a track is skipped, the small thumbnail icon for that track becomes blue as if that track has no thumbnail, but all my files have embedded thumbnails. When I click again on the same file, it starts playing and the thumbnail is visible.

Another thing I noticed is when I start a new playlist, the first track is also always skipped.

Any ideas?

Thanks.

You may want to try turning off SetNext support for that zone in the DLNA Controller options (right-click on the zone).

Hi Bob,

Maybe I was not clear but I'm using the DAC USB connected using alsa (hw:CARD=NA11S1,dev=0 [ALSA])

Best,

Please provide a screenshot of the Audio tab of MC options, and of the Device Settings dialog accessible from that page.

If you also have MC running on something else like a PC, I would try plugging the Marantz into that and see if the behavior is identical or not.
