"Clicks" after 5 or 10 minutes on MC 26 on RPi4B

<< < (2/2)

JimH:
Multi-channel on an RPi could be borderline.    You could try turning off any background processing.  Import, audio analysis, etc.

Zhillsguy:
I also recently got a Pi4 4GB.

Although much better than previous versions, it is a very low power device with limitations. I installed the latest Raspbian, which is very lightweight. I use an external USB DAC (Scarlett 6i6) and occasionally music would "drop out" for a few seconds, both listening to Radio Paradise and from local network (all wired gigabit).

I installed DietPi running LXDE, even lighter weight than Raspbian, and I noticed an improvement well worth the effort. I think MC performance in general will be improved a little when the Buster version is released.

If you have an extra micro SD card, maybe try another OS, or get an external DAC that natively supports decoding whatever format you are sending to it? Another option is (using MC) to convert the files to a reduced bit-rate format that the pi can handle, if what you are hearing is performance related. You want to avoid the pi doing any on-the-fly bit rate conversion if possible.

bob:
I'm actually pretty amazed the Pi4 plays multichannel through HDMI. That's a change in the kernel for sure from the Pi3 Jessie distro.

I have one of the Hifi berry boards on a pi 4gb and donīt really have any playback issues. I play mixture of mp3 and flac files that come over the wire with no prior decoding. Only dual channel, but I mean it does not really break a sweat doing that.

I think this does not have anything to do with power, the pi should be plenty powerful to playback music (just the onboard DAC/AMP s*cks). My bet is on itīs the USB ports/controller. I have the same issue on my desktop when connecting my jotunheim to a USB 3.1 port I get the occassional audio dropout. On USB 2.0 no problem what so ever. Thatīs on a x470 crosshair VII hero, so itīs also not like I cheaped out on the board or anything like that. USB ports sometimes are just a bit picky. I do have another standalone DAC now, could try that on a USB 3.1 port if I see the same problems. But I donīt think I would. Itīs like the known working USB stick I own that on some computers I canīt use to install an OS for some reason and on others it works.
