A quick Q about the usb interface: what bits per sample are supported? 16, 24, 32?
On Linux (raspberry pi and fedora) when i try to play a ripped CD track, 44.1k 16bit wav, using ‘aplay -Dhw:1 foo.wav’, it complains that only S32_LE format is supported.
sure enough use sox to generate and send 32bit 44.1k or 48k wav and audio is happy.
is this my misunderstanding, a kernel driver issue or does the E30 only support 32bps on the USB interface?
this is a 2006xxxx unit
Only 16 and 32. You can use -Dplughw:1 to do the format conversion.
