Re: my asoundrc is modified every reboot

There is some kind of bug in the lxpanel volume applet, that keep on thinking that your sound is not working, and then attempt to replace the .asoundrc with some working default settings, ignoring if there already is one. Do this: * Remove the volume applet from the lxpanel * replace the correct .as...

Re: omxplayer plays a little fast.

@di512 If you still have problems with omxplayer playing the files too fast, could you run omxplayer with the -g option, and post the omxplayer.log? Looking at E3V3A issue, I found a small problem with omxplayer. With your log I want to verify if that is also causing your issue. Thanks in advance. ...

It is NOT a fact that node.js, npm, or any of it has to be installed as root. Generally speaking you are right, but that create a bunch of problems with the already installed (from distro stuff).

Re: omxplayer plays a little fast.

Apparently omxplayer ignores the embedded sample rate and continue to use 44100 Hz, thus speeding through the file 2 respectively 4 times as fast. Doesn't seem to be any solution to this.

The release date of 99% of the firmware files IS the version shown.
Surely 20161130 is not the release date that was pushed to us, only a few days ago! :D

Since, doing "apt show firmware-brcm80211" doesn't show anything useful (in this regard) at all!

Re: Impedance of GPIO lines

Great question and lots of good info here. However, a correct and precise answer is still not seen. Reliable operation with a clock at 100MHz is probably beyond the scope of the GPIOs brought out to the 40-pin header simply because that sort of header isn't designed to carry signals at that frequenc...

Re: USB Gadget Mode on Compute Module

No. There is only one USB peripheral on the BCM283x SoC. On the CM, A, and Zero that is exposed directly to the outside world, so these tricks can be played. On any B, B+, 2B, or 3B there is an SMSC951x chip connected to it to act as a USB hub and network interface. You therefore can't switch the f...

Re: Can I use Raspberry Pi model B as slave(gadget) device?

The schematics for the USB data and OTG lines will be similar, if not identical, to that of the original Pi A/B ones. The OTG USB_ID line is grounded close to the chip, which means you can't get normal OTG function without hardcoding it (as has been used on the A and A+ models). Great! So looking a...
