Maximum SD card interface speed

Hello,

Technical question: What is the maximal speed of SD card interface in PI3 and Pi4 SoC?

Is it a good idea to use high speed cards, designed for 4K video cameras? They're designed for handling videos at 30Mbit or more on the fly.

Re: STICKY: Setting up HDMI output when video output is wrong.

I have two problems with Pi4 and Buster:

No audio over HDMI, even if forced to HDMI by raspi-config.

My display supports both 60Hz and 50Hz modes. With Pi4, it boots into 60Hz always. Is there a chance to make it to prefer 50Hz modes?

Is the source of rtl8192 driver available, in the case I will build my own kernel?
rtl8192cu or rtl8192eu?

Re: Building crazycat's media_build on RPi3

Same result here. Lot of 'disagrees about version of symbol ...' in DVB stuff.
Maybe there are some differences between version of kernel and the headers.

I tried this both with pre installed kernel and with update && upgrade (which installs a bit newer kernel). With the same results.

Hi, I am really happy that someone else has this tuner. Evolveo is a private brand of Czech company Abacus. Aren't you from Czech republic?
I didnt know it about Evolveo.
Yes, I am from Prague.

This tuner is better in sensitivity than the PI DVB Hut and the most TVs
