How is this today? Can 24 bit/192kHz audio played using ALSA over HDMI now? Not trivially through alsa. It can from openmax. There do exist kernel patches that enable higher bitrates and multichannel through alsa, but they didn't play nicely with sonic pi so haven't yet been merged, but it's someth...

So, can anyone with unreliability try running memtester as requested by Phil.

If it does pass can you try again with: sdram_schm...

Re: Moving Linux kernel to 4.14

I really wonder when the VC4 driver will get out of the experimental stage and become the default, and stable. Is there an effort to test it in a public/organized manner, so we can help with feedback? While the vc4 driver is working well for most for most desktop apps, there is still work ongoing t...

Re: Raspberry Pi 3 B+ lockups

[*] (OKAY) with "arm_freq=1200" and "sdram_freq=450" --> system was running very stable - but also not very performant of course. So I assume just adding arm_freq=1200 makes it stable? If so, you could try removing arm_freq=1200 and adding "over_voltage=2" which may make it stable without affecting...

This is the sound applet menu, and clicking vc4-hdmi has absolutely no effect, other than closing the menu.

vc4-hdmi isn't a default option in that menu. Did you enable the experimental vc4 graphics driver?

If you are having reliability problems can you try editing config.txt sudo nano /boot/config.txt and add to end of file: arm_freq=1000 and reboot. Does that avoid the issue? If it does can you try removing that and adding: over_voltage=1 if that doesn't help then you can increase to 2. Let us know i...

Re: RPi 3B+ Heat/CPU related improvements.

So, generally speaking, a Pi 3 B+ without heatsink still cooler than an aluminium heatsinked Pi 3B? If the heatsink is a small and sticks onto the SoC then I'd expect the Pi3+ to be much more effective. If the heatsink is large (e.g. attached to aluminium case like the FLIRC) then it's not clear an...

Somewhere it says that the extra current is going into the new USB/LAN chip.
Certainly some of it. EEE is supported.
If the switch you connect to supports it you save about 0.5W.

However the PREEMPT and PREEMPT_RT kernels are still showing the crash as posted above.
So are you using our kernel tree unpatched, or is that a tree modified with RT patches?
The RT patches are not supported by us and not expected to work with fiq based USB driver.

Re: Moving Linux kernel to 4.14

4.14 is now on the master branch of rpi-update.

Code: Select all

sudo rpi-update
is enough to get the 4.14 kernel.
