Hi list, I have a USB sound card that I want to get 5.1 sound working on. Specifially, it is a Hercules Muse Pocket USB, recognised by lsusb with the correct name. I have tried many different suggestions for asound.conf, but none seem to get me more than 2 channels, so I think the problem lies deeper. Alsamixer also displays only two channels. The card uses the generic USB-audio driver, and 2 channels work fine. What is interesting, is that cat /proc/asound/card1/stream0 gives me: Playback: Status: Stop Interface 1 Altset 1 Format: S16_LE Channels: 2 (...) Interface 1 Altset 2 Format: S16_LE Channels: 6 (...) Can I somehow "force" the card to use the second Altset, which has 6 channels? What are these Altsets anyway? Some more info: aplay -l: card 0: Intel [HDA Intel] (...) # The built-in card card 1: Audio [USB Audio], device 0:USB Audio [USB Audio] Subdevices: 1/1 Subdevice#0: subdevice #0 dmesg shows some generic info about the bus, and then usbcore: registered new interface driver usb-snd-audio Any and all help is appreciated, and I am happy to provide more information.
