Re: analog Sound Raspberry PI 4 is mono, not stereo

Since on my Pi4's default Raspbian installation I use the XFCE desktop (apt install xfce) which in-turn installed the package "xfce4-pulseaudio-plugin", which in-turn installed the package "pulseaudio", I too have no stereo but just mono sound on the Pi4's analogues audio socket. However, the soluti...

Re: Shutdown Pi4 but network's yellow+green LED stay active, after today's firmware update?

Thanks for the explanations. Also problem solved. Furthermore, with the Pi we're always learning more things about Linux, boot procedures, computers, etc. Very interesting and very helpful.

Re: Shutdown Pi4 but network's yellow+green LED stay active, after today's firmware update?

Thanks Timg236 and Rpdom for your help. So I just flashed (for the first time manually) the Pi4's EEPROM, like explained in the fine "Pi4 Bootloader Configuration" document, and it worked fine! Now when the Pi shuts-down, its network's green and yellow LEDs go off, like it used to be before. Just ou...

I see. Thanks Rpdom.

Does your Pi4 (in case you have one) too show the new network LED behaviour when you shutdown the Pi?

Re: Shutdown Pi4 but network's yellow+green LED stay active, after today's firmware update?

Thank you for the reply. So do I understand it correctly that this is a new behaviour with our Pi4 due to some firmware change in the recent few days? And if I wanted to have the old behaviour (i.e. yellow+green LED go off after the Pi's shutdown) I would have to follow the steps mentioned in your l...

Shutdown Pi4 but network's yellow+green LED stay active, after today's firmware update?

So far with all my Pi devices, when I shutdown one (for example with "sudo poweroff"), the SD-card's green LED blinks a few times and then goes off, and also the network socket's yellow LED and green LED (which shows network activity I think) go off. This morning I did an sudo apt update sudo apt fu...

Re: Ubuntu 19.10 (Eoan Ermine) released

Therefore Raspbian will always be (should always be) the default choice for an RPI user, and that is why it doesn't get prominence here, not because we are "illogical beings". Prominence was not my point, but that the user Pulsar got some unlogical negative waves for asking a simple Ubuntu-for-Pi q...

RSS feed for new threads on the forum?

So the forum server (raspberrypi.org/forums) doesn't provide a RSS feed for new threads on the forum, it seems.

However, is there another way, maybe? Like an external RSS feeder which could read the new threads here and provide them as a RSS source? Any hints welcome, thanks.

I'm running a standard Raspbian on a Pi4 and it works so well already in 32bit. I've used and still use the older Pis (Pi1, Pi2, Pi3) but clearly the Pi4 is the best of them: not only because it's the most powerful Pi model but also because Debian based Raspbian 10 is so mature and works so well wit...

Re: free some RAM

Have you installed the downloaded ".deb" file?
Like:

Code: Select all

Maybe a re-boot is neccessary afterwards.

Re: free some RAM

zram usually helps, too, in particular for machines with not-so-much RAM. If I remember right, it's been part of previous versions of Raspbian, and it's still in Debian-based Ubuntu, so depending on which Raspbian version you use, you could activate it via: sudo apt install zram-config To see what ...
