Hello. I am using baresip for SIP communication. I have faced a problems with audio USB adapter (http://www.hardkernel.com/main/products/prdt_info.php?g_code=G141629380416) with C-media chip. I have set it as default sound card. I make a call using baresip. Until I answer the call on another device it works, it rings. But when I answer, kernel errors occurs and Orange Pi hangs (cannot do anything): Message from syslogd@localhost at Sep 18 11:20:18 ... kernel:[ 226.378730] sunxi oops: enable sdcard JTAG interface

Thank you in advance

Thank you for answer. Yes of course, resistors Could you recommend any amplifier?

Hello everyone. I have a question for people who already managed connecting audio to Orange Pi One. I have started with audio output. I have tried to connect like on picture, but without capacitors and coils (because I don't have it at the moment, have to buy ). Should I hear something with speaker-test -c 2 ? I haven't hear even any noise. My connection is correct? With the MIC. Have you used circuit shown on picture? I will appreciate if you could give me any tip. Thank you in advance. maciejos
