I am using a USB sound card with the squeezelite player. The card specs state that it is capable of playing „virtual surround 7.1“. However, when I specify sourround71 in the max2play parameters, the following error occurs:
Update Configfile – existing Entry changed
Updated Squeezelite Settings – Restart Squeezelite to apply changes!
Trying to stop … successfully stopped
Trying to launch … NOT successful Click here to show detailed information
[15:57:23.388509] test_open:316 hwparam init error: Invalid argument
[15:57:23.388708] output_init_common:382 unable to open output deviceThe card does play when I specify dmix or hw, but the max volume is low and it cannot be adjusted using the volume controls on the card itself. What parameters should I add so that the card will function correctly?

Bus 001 Device 004: ID 1b3f:2007 Generalplus Technology Inc.23. April 2019 at 12:23 #45110Hello ehrnfldm,
What is the name of the card? Does the manufacturer have any specific software or drivers for it?
How did you activate the card? Did you install the USB sound card driver from the Raspberry Settings?
23. April 2019 at 14:28 #45120Thank you for your prompt reply. The only writing on the card is „7.1 channel sound“. The accompanying paper card in the package states that no drivers are necessary. The manufacturer’s name is not mentioned anywhere. I discovered it when using the lsusb command: Generalplus Technology Inc. I just installed the usb sound card driver from the Raspberry settings and rebooted. This had no effect. the same errors appear as before when choosing option surround71 for the squeezelite sound card.
24. April 2019 at 9:40 #45125Oh sorry, I thought you weren’t able to load the different channels. Surround sound is an exotic solution for Squeezebox. Here’s what I wrote on the subject last year:
So far, there has not been a lot of requests for 5.1 audio playback in our community. Most audiophiles prefer 2.0, or in some cases 2.1, for which we created the Piano 2.1 DAC solution.
There is this solution, which should work for Max2Play as well. But it is rather niche.
But generally, Squeezebox was designed for 2.0 playback and your best bet for anything with surround sound is using Kodi 😉
Some people use 7.1 cards to play to different channels with different players. But surround sound for music is not a usual application.

24. April 2019 at 11:54 #45130I really have no need for 7.1 sound. It just so happens that the sound card supports it. The maximum volume was quite low so I thought that the card was not configured properly. In the meantime, I wanted to compare the sound to that put out by the raspberry pi audio. I set enable audio in the raspberry pi settings, but no sound. I removed this setting and this resulted in a boot loop. In any case, can you recommend an inexpensive sound card which would be supported by max2play?
24. April 2019 at 12:02 #45132Your sound card should be supported as well. Just select one of the channels that pop up after rebooting with the USB sound card selection loaded in the Raspberry Settings.
For ideal sound, we recommend using a GPIO HAT sound card that is mounted on top of the Pi. You can have a look at our product range in our shop.
24. April 2019 at 14:48 #45139Please help! I rebooted the pi with a fresh image of max2play. On the settings menu, no data is saved. I cannot save my email address to active my license, nor can I change the region.
24. April 2019 at 16:30 #45140Update: I flashed another image and all is well. Must have been a bad image. In any case, I can now begin customization. I would like to address another squeezebox issue. My original configuration for the squeezebox was a QNAP NAS on which I ran a squeezebox server app provided by QNAP. This worked fine for several years until a recent hard drive failure on the NAS. Then I discovered that QNAP no longer provided a server app. In searching for a solution, I found the option of Raspberry Pi. When using the qnap app, Hebrew fonts were correctly displayed on the squeezebox boom. With the server on raspberry pi, all letters are in English. What determines the fonts? Are there perl libraries which should be added? Any assistance would be very much appreciated.

You are probably going to get the best and quickest answer on this specific question from the Squeezebox experts over at the SlimDevices Forums.
