Hello @jose_manuel_gallardo,
You are doing great! Please don’t worry—handling terminal commands can feel intimidating, but you are looking in exactly the right place.
You are completely right to be cautious about editing that container file. As it turns out, the USB power-saving feature isn’t actually happening inside the Roon container itself—it is being managed by the main host operating system of your QNAP NAS. Because the NAS hardware controls the physical power to its own USB ports, when Roon pauses the music, the QNAP thinks the port is idle and cuts the power connection to your amplifier. When you restart the whole NAS, it wakes the port back up, which explains why it keeps temporarily fixing the problem.
To permanently stop the QNAP from turning off your USB audio port, we need to run that command directly on the NAS system. Here is the easiest way to do it:
Step 1: Enable SSH Access on your QNAP
To send a command directly to the NAS operating system, we need to briefly turn on secure remote access:
- Log into your QNAP desktop in your web browser.
- Open the Control Panel and go to Network & File Services > Telnet / SSH.
- Check the box to Allow SSH connection. (You can leave the port at 22).
- Click Apply.
Step 2: Run the Command (From a Windows PC or Mac)
- If you are on Windows: Press the Windows Key + R, type
cmd and hit Enter to open the Command Prompt.
- If you are on a Mac: Open the Terminal app.
Type the following command to connect to your NAS (replace YOUR_NAS_IP with the actual IP address of your QNAP, like 192.168.1.50) and press Enter:
ssh admin@YOUR_NAS_IP
It will ask for a password—type your main QNAP administrator password and hit Enter (you won’t see the letters appearing as you type, which is normal security behavior).
Once you are successfully logged into the QNAP console, simply copy and paste this exact line and press Enter:
echo -1 > /sys/module/usbcore/parameters/autosuspend
This instantly tells the QNAP’s hardware engine: “Do not ever put the USB controller to sleep.”
Step 3: Turn off SSH
Now that the command is sent, go back to your QNAP browser tab, uncheck the “Allow SSH connection” box, and click Apply to lock down your security again.
Try leaving your amplifier idle for a few hours now without playing music. When you open Roon later, your USB zone should remain perfectly active and ready to play without requiring any more frustrating NAS reboots! Let us know if you hit any snags during the SSH login.
