I bought a USB audio adapter and have been unable to get any sound to come out of it.
lsusb reports it as:
Bus 001 Device 005: ID 1b3f:2007 Generalplus Technology Inc.
which is not one I've come across before.
Anyway, I modify
/etc/modprobe.d/alsa-base.conf, reboot, run
amixer and get the following output:
Simple mixer control 'Speaker',0 Capabilities: pvolume pswitch pswitch-joined penum Playback channels: Front Left - Front Right Limits: Playback 0 - 30 Mono: Front Left: Playback 27 [90%] [-4.50dB] [on] Front Right: Playback 27 [90%] [-4.50dB] [on] Simple mixer control 'Mic',0 Capabilities: pvolume pvolume-joined cvolume cvolume-joined pswitch pswitch-joined cswitch cswitch-joined penum Playback channels: Mono Capture channels: Mono Limits: Playback 0 - 14 Capture 0 - 30 Mono: Playback 0 [0%] [-12.00dB] [off] Capture 26 [87%] [27.00dB] [on] Simple mixer control 'Auto Gain Control',0 Capabilities: pswitch pswitch-joined penum Playback channels: Mono Mono: Playback [off]
I also get the following from

Looking good, however I get no output when I attempt to play a sound:
pi@raspberrypi ~ $ aplay /usr/share/scratch/Media/Sounds/Vocals/Singer1.wav Playing WAVE '/usr/share/scratch/Media/Sounds/Vocals/Singer1.wav' : Signed 16 bit Little Endian, Rate 11025 Hz, Mono aplay: set_params:1087: Channels count non available
I've set the volume on
alsamixer high enough so I should be hearing something.
At this point I've no idea whether or not I have a broken USB audio dongle or configured something wrong. Can anyone help?
