I'm currently trying to use a Logitech S-150 USB Digital Speaker. Unfortunately, the volume range is way off, i.e. only 1% and 2% settings in the alsamixer are actually usable for general playback. dmesg: ----- [ 9850.768093] usb 1-1: new full-speed USB device number 2 using uhci_hcd [ 9850.948103] usb 1-1: New USB device found, idVendor=1130, idProduct=1620 [ 9850.948123] usb 1-1: New USB device strings: Mfr=0, Product=2, SerialNumber=0 [ 9850.948138] usb 1-1: Product: USB AUDIO [ 9852.353857] hidraw: raw HID events driver (C) Jiri Kosina [ 9852.397038] usb_audio: Warning!

If you need any additional information or someone testing a kernel patch, just let me know. Cheers, Linus PS: My current workaround is to use more fine grained settings via amixer. --b5gNqxB1S1yM7hjW Content-Type: text/plain; charset=utf-8 Content-Disposition: attachment; filename=lsusb-vvv sudo lsusb -vvv -d 1130:1620 Bus 001 Device 005: ID 1130:1620 Tenx Technology, Inc.
