That is to be expected, the player can only output to HDMI and Jack. I have a USB sound card on my Pi, but I can't hear any sound of the splash video Raspberry Pi (any version), Odroid C2 and XU4. But we won't add some per-user driver for fancy devices. The compatible devices will improve with Recalbox updates (kernel, drivers. The best is to burn the image as explained above and try by yourself. As a general rule of thumb : if it works with Linux, it should work with Recalbox.
None ! The PC world is so wide that we can't provide a compatibility list. Please take good care : all your storage devices will be listed, even your system hard drive !

If your device is not listed in Etcher, go to Options, and enable the Unsafe mode. It's the very same procedure as other platforms ! Plug your USB storage device (USB key or hard drive) and write the image as explained on

The 4.0.0 release was such a huge success that our servers were overwhelmed by the requests. The update is progressively made available to everyone. It's way beyond the release time, and still no update showing, why ? In that case, just change you updates.type to stable in the nf The only ones who can do the upgrade are those who upgraded from 4.0.1/4.0.2 and were on the last unstable we released back in april. people who upgraded from 4.0.x to unstable have better chances to update.some people still have a very early unstable 4.1, you won't be able to upgrade.If you were using an early one, you'll have some silent trouble while upgrading and won't notice it, making the upgrade partial and really buggy We wouldn't recommend you upgrade from an unstable version for MANY reasons : I'm on 4.0.0 (or even before), can I upgrade ? As usual before a major update, we strongly recomment you make a backup of your data Recalbox version before upgrading As you may have some questions before upgrading, let's try to summarize all here ! Feel free to ask questions related to 4.1, we'll eventually update this post to add them. As some of you may know already, 4.1 will be released on 13th of October 8pm CET.
