Pullup resistors for GPIO ports no longer initialize since kernel update

I am running a Raspberry Pi 4B with 4 GB of RAM and running Raspbian Buster, and I use two of the GPIO (17 & 18) ports to monitor the status of two switches that when enabled connect the GPIO pin to the Pi's ground (I also use pins 22-25 but they are connected to different types of switches that...

Re: What is the secret to playing 5.1 audio on a model 3B+?

Well, I again started out this morning with a fresh install of Raspbian and tried adding those things to the start of /boot/cmdline.txt. After booting up the system I found that Volume Control showed no output devices at all, although you could go and select a PCM device but that gave the same thing...

Re: What is the secret to playing 5.1 audio on a model 3B+?

I understand about the passthrough mode in Kodi and have in fact used it on a HTPC, but that is not what I am looking to do here. I should probably mention that this appears to be a Raspberry Pi specific problem. In trying to run this down and make sure it was not an issue with my AV Receiver or TV,...

What is the secret to playing 5.1 audio on a model 3B+?

I tried posting this in the Graphics, sound and multimedia section and got no response so I'm hoping maybe someone here can answer. I am at my wit's end after trying for two solid days to get my Raspberry Pi 3B+ to play 5.1 audio out of the HDMI port. The real issue is that the Volume Control (a.k.a...

Re: Is there any way to downgrade LIRC to an older version?

Oh... well according to that 0.9.4c is from October 2016 and this only started giving the error a couple months ago at most. So maybe it wasn't a version upgrade of LIRC, but something else, but if that's the case I have no idea what the problem is. This is a case of nothing has been changed, other ...

Re: “mount error(112): Host is down” on stretch, but not jessie! Why?

Try changing vers=1.0 to vers=3.0 (or 2.0). Microsoft has deprecated 1.0, though I'm not sure why it would work on one system but not another.

Suggestion for potentially useful hardware addon

I don't know if anyone else would find this useful, but there is a particular hardware add-on that I would like to see for the Pi. In its most basic form, it would connect to the SD card slot and on the other side present a USB port to which an external hard drive could be connected. The purpose wou...

Re: Backing up the SD card - what's difference .bin vs. .img

To summarize, I think what is being said here is that you could create a batch file as follows (assuming that cifs-utils has been installed and you want to keep one current plus two older backups): #!/bin/bash mount -t cifs //local_ip_address/share_name/backup_directory/ /mnt/ -o username=home/usern...

Re: Backing up the SD card - what's difference .bin vs. .img

1) Yes - "cp" and "dd" will create the exact same file. And, as I said, the syntax for "cp" is easier, so there' s really no need to use "dd" for this task (or any tasks related to the making or saving of images for the Pi). Note to nitpickers: I didn't say t...

DetlevSchm, I also apologize if I am a bit touchy.
