Thanks for the info. I am trying to vi /etc/asound.conf but its read-only. Do I need to boot into single mode to edit?

Here is a mount output.

mount

I know I'm going against the grain here, but I am trying to get http://recalbox.remix.free.fr/ this installed on an HP Probook 430 G3 laptop. The audio worked when I plug into the 3.5m jack, but it wont output through HDMI or the Laptop speakers. I kinda expected the laptop speakers to not work, but Ive had other laptops audio work in Lakka so I hoped for the best. Without looking into the exact audio devices, I know the audio is using Conexant High-Definition, if it matters.

How might I get the audio working for HDMI or laptop speakers? Thanks!

I was trying to install on a Dell Inspiron 3558 Laptop i3-6001U with Intel HD Graphics 5500. It was a black friday deal, and I figured I could make a portable setup for Recalbox and play it on any TV. I returned that laptop and found another.

The new laptop (HP ProBook 430 G3 (i5/HD520) which did boot from 32GB USB, but it doesn't support SD boot, which is a b*mmer. At least it booted though, so I guess this is/was some sort of hardware problem with the Dell, as stated.

I was using the x86 64 to boot off a USB, based on the instruction off the link I posted before. I also get this error when using the SD boot though, again using the instruction on my last link. Thank you.

I am trying to install Recallbox on a new dell laptop, and no matter what I keep running into an error when booting to either the SD card, or USB that says "Invalid partition table!".

I have tried both methods on creating the USB or SD from the link below. I have also used two different USB cards, but just one SD card. https://github.com/recalbox/recalbox-os/wiki/Installation-(EN)

I will mention, I currently have Lakka installed on the internal 1TB hard drive of this laptop, so Im curious if that is causing an issue. However, like I said, I get this error when booting from either of the USBs or SD card.

Any help is appreciated!
