We designed an embedded board for RK3288 with codec chip(tlv320aic3007).The sound of the speaker is particularly low when playing music。The chip's power supply voltage is normal。The audio chip driver reported an error while the system was running。 “tlv320aic3x-codec 2-0018: Failed to init class D: -6”。Please help analyze what is causing this and how to solve it. Thank you!
