This is caused by inadequate power. Use a good power supply and a good power cable. Some USB devices require a lot of power, so they must be used with a powered USB hub.

This is caused by inadequate power. Use a good power supply and a good power cable. Some USB devices require a lot of power, so they must be used with a powered USB hub. Some cheap USB hubs suck power from the Raspberry Pi even if a USB power supply is connected.

Device drivers for sound are still being developed. Please wait for the community to improve the situation.
