If your running Jessie or Stretch Lite there won't be any icon. Typing alsamixer and hitting enter should get you an option to adjust sound level though.

I have all kinds of text files with how to's littered about in My Documents Pi folder. Probably should clean things up, ......... some day.

ok, that worked i get the alsamixer . its at 100% , arrow up -down to adjust it thanks

i was just going to post that ,Very disappointingNo Pi 4

Yeah, that is a bummer, not even a 3A. Maybe something will drop on Monday? Not likely, but we can always hope, or pray, lol.

I haven't tried using a 3B as my regular PC. Just having to go back to a single monitor makes me not want to do it. Spoiled I guess. They work great for what I do, do with them though. I was hoping for a 3A to be released. I have two A+'s I'd swap out for 3A's. I really thought they would do a little more than just blow out some candles though?

Pimoroni shop now shows in Canadian dollars,,,,

It will show in what ever you want it to. Click the flag to change it to Euros or GB Pounds etc. That's been there for a while now. It will switch back to GBP when you go to checkout though. It's nice to see what its going to cost you in CAD though without having to get a calculator.

If you haven't logged in for a while it was likely on GBP, then when you logged in it toggled to CAD. Did you change it or did it change on its own?

I'm not sure if this new, or I just missed it the first time around.
Access the GPIO pins on a Pi Zero from your PC, or double the available GPIO's on a Pi 3!

Using two Pi devices together

As well as using GPIOs from your PC, you can connect a Pi Zero to another Raspberry Pi and use two sets of GPIOs together, controlled within the same script. This is similar to the principle of remote GPIO, but instead of using Pi devices over a LAN (local area network), where each Pi has to be running Raspbian from an SD card, this method again just requires a Pi Zero and a USB cable.
Now boot a Raspberry Pi (e.g. a Pi 3) running the latest Raspbian Stretch. The Pi Zero tool is not pre-installed in Raspbian, so you’ll need to install it. Open a Terminal and type:

sudo apt install usbbootgui -y

When it’s booted, connect a Pi Zero with a USB cable and this time, instead of setting the default pigpio address and pin factory, you’ll define that within the code.
