Website now updated: OK.

On the website, in the "Repositories" section, there are 3 simple CLI. The first line is missing a "sudo". This could be bad for newbies as they get an "Error: must run as root" without any other hint.

Those 3 CLI should be:

sudo add-apt-repository ppa:jonaski/strawberry
sudo apt update
sudo apt install strawberry

(Simply add "sudo" to the first line as i did here, please.)

Sorry for being so "beginner level", but let me start with some basic clarification. Maybe this is just a language issue ?

Mute, definition: «turn off the sound» or reduce the sound volume to zero.

So, of course it is a normal behavior that the sound is still playing in the background, and the player is still moving forward on the track. You just don't ear it. Example: you mute for 10 seconds, then "un-mute", and find you lost 10 seconds of track playing. This looks normal to me.

I did the test on LinuxMint 20.3, Strawberry 1.0.4, with an MP3 in my Collection. Mute worked as expected. It is the same action as lowering the volume to zero.

EXCEPT: I found something strange when doing this test. This was only a quick test, so i did mute/unmute for only 10 seconds or so. I have the «Block analyser» on. You know, this cute animated instant frequency spectrum bar graph... Well, i found it freezes for a few seconds after unmute. But the sound is okay. It is just a little visual annoyance. Some unpleasant delay before getting this visual gadget back to work. AND, also, i tried this equivalent to mute: lower the volume control all the way down to zero. I waited for a few seconds and then i put the volume control back up. Well, i found there was a delay before the volume gets back to 100%, not just 50% or so. And the «Block analyser» was frozen for a few seconds just like it did with the mute/unmute test.

OTHERWISE: There is no problem at all when i just lower the volume to some low but not zero level, and then put it back up. I get instant accurate response for both sound and visual effects.

Post-Scriptum: If you just wanted to turn off the music for a few seconds, without skipping any time on the track, then just press PAUSE... This works fine ! Of course, i could argue i am apparently loosing 1 or 2 seconds on the track, but that is because i turned on the Fading effect in Tools > Settings > Backend. This sounds normal.

Ah, okay, now i found some more precise information, crawling into this PayPal labyrinth.

So, i logged into my PayPal account, then clicked:
Send and Request > Fees (at the bottom of the page) > Sending and receiving

And i finally got onto this page:
https://www.paypal.com/webapps/mpp/paypal-fees

This looks quite complex for someone who is not passionate about PayPal transactions... There are many different cases: commercial or personal, foreign or domestic, bank account or bank card or credit card...

So, here in my case today, i did it this way:

Sending international personal transactions > Europe or USA (i guess ?)
Payment method: Cards (credit card here)
Rate: 2.99 CAD + 2.90% + fixed fee (fixed fee: a small 0.35 EUR or 0.30 USD or similar)

● ● ●

Maybe i could have considered this a commercial transaction ?

When «Buying with PayPal», there is «NO FEE», except... a currency conversion fee of about 4%... And i think i remember reading somewhere else that the "merchant" would have to pay something... So, in doubt, i didn't do it this way! Anyway, i don't even know if that was possible or not, in this case !?

Sorry for all this big load of information. I am also writing this for myself, to remember all this next time... Well, at least i did finally make my small one-time contribution

Ah, okay, i had a discussion on PayPal messages, and searched on their website. And i also made some dummy, cancelled sending for testing purposes. So, now i guess i am starting to be just a bit less messed up.

I got mixed up with conversion fees versus transaction fees. The conversion fees seems to be reasonably small. If i send 10 $ CAD it gets converted to 7.54 $ USD. That's a 0.37 $ USD fee or so. No big deal. But the PayPal transaction fee is much heavier. That's my problem. Apparently, there is a 3 to 4 $ CAD extra charge because i only have my credit card linked to PayPal, not my bank account. Again, that's just my problem. I could possibly try with my bank account, but later. For now, i will just go with my PayPal account, linked to my credit card, and end up paying 14,11 $ CAD to send 8,00 $ USD. Now done !

Still, maybe it would be nice to know what currency Jonas Kvinge would prefer. But that doesn't seems to be very important. That's just an extra mouse click and a few cents lost in conversion fees.

Hi, sorry but i am just a poor little man. I just wanted to make a small contribution of 5 Canadian dollars (CAD $) or so. An almost symbolic, one-time donation via PayPal. I don't even know where Jonas Kvinge lives, so i tried to send US dollars (USD $). But i got discouraged when i saw there was a conversion fee. I cancelled. I was thinking, what if there was i conversion fee on the other end too? Example: i send 5$ CAD - 3$ fee ≅ 1.50$ USD - 2€ fee = some negative result when reconverted to euro (€).

Which currency should i send via PayPal: $ CAD, or $ USD, or € euro ? or other ?

Of course, i asked these questions on PayPal first, but they answered with instructions on how to move that mouse, reach that button, and click on it... LOL !
