Thanks for the post and experiment. Estimated cost? Might want to check fan blowing both into and out of enclosure for energy and cooling difference.

Pick a HAT or USB audio card. Try Moode Audio dedicated audio software.

Qty1 is always $5. Except on pi day when it is $3.14. Can't seem to leave the store without one.

I'm running without a heat sink, but with a fan blowing up direction in a open walled case and temp stays in low 40's.

By the way, if you run "sudo ./vl805" with no parameters it displays the version of the currently running firmware. Note that this may differ from what's in the EEPROM if you've just reprogrammed it but not rebooted.

VL805 FW version: 000137a8

Today reflashed Raspbian Buster desktop. FLAC files from original source are now playing fine in VLC with Pi4 4 GB RAM. Files that were transferred previously still do not work. Something was wrong with the file transfer which corrupted the FLACs, don't know what it was. Go figure.

You did reboot after editing /boot/config.txt?

Yes

Did you test with the memory settings described above?

Sorry, didn't see that suggestion. Yes, changed to total_mem=1024, still gaps in playback on pi4 4 GB RAM.

0.357 watt difference is significant.

Anyone else having audio challenges on a 4 GB RAM rpi4 running FLACs with VLC?

energyi

How they can be identified?`

energyi

Saw the official case and thought that the pi4 is going to need a fan because my temps were already higher than I like without a case so didn't purchase. The outdated octane scores I posted didn't include any case in a relatively cool room.

energyi

Yes, had a USB 3.0 thumbdrive and USB 3.0 Hard drive connected. Put the FLACs onto the desktop, shutdown, removed t he USB 3.0 devices. Still, FLAC over VLC doesn't work properly, gaps, jumps.

Again, worked on 1 GB RAM with USB 3.0 devices, not working on 4 GB RAM. Thanks.

energyi

Temperatures? Looks good, thanks for sharing.

energyi

Any reason a FLAC file plays with gaps on a 4 GB RAM Rpi4, but works fine on 1 GB RAM version? Same microSD card, VLC player.

energyi

Outdated Octane Benchmark Score on Raspberry Pi 4 4 GB RAM is 8454.

Just trying to show rpi scores. Yes, have lots of other scores from other OS and boxes, but hoping this is helpful to the Rpi community to compare and contrast old benchmarks to new 4 versions.

Previously wrote: Audio output from 4B is excellent. That was running FLACs with VLC. However, that was on a 1 GB RAM. With a 4 GB RAM rpi 4B the audio output is bad. Gaps, skips. Don't know why it was different, microSD card and USB 3.0 thumb-drive and hard drive is exactly the same. You would thin...

Thought if anyone was interested I would post my Octane Benchmark score for the Raspberry Pi 4 1 GB RAM straight out of the box, no logging into anything, just going immediately to http://chromium.github.io/octane/. Score for the Raspberry Pi 4 1 GB RAM was 7652. This benchmark is outdated, but I st...

If you are like me, you might not have gotten access to the higher GB Ram models because they were sold out. The 1 GB RAM version seems good in its own right; audio is surprisingly good! Purchased a 64 GB Class 10-UHS-1 microSDXC card which I am hoping can somehow make up for the reduced onboard RAM...

Light duty web, No case, horizontal Rpi4 1G version 57 C and 56.5 C:

Code: Select all

pi@raspberrypi:~ $ vcgencmd measure_temp
temp=57.0'C

Great job by the Foundation to keep this quiet, something the bigger companies can't do. That itself is a valuable performance.

Can't wait to team the 4 with a Coral usb.

energyi

Thumbs up, great work on the sprinkler.

energyi

Very nice work for your sleep study. Are you planning to open source the code and packaging? Could be valuable for other applications. I like the idea of monitoring car indoor conditions, and possibly have a pm 2.5 sensor added. Using BME280's for humidity control on a swamp cooler. Also BME680s are...
