Is there any way to enable/disable UAC1 when headset plugin/plugout?

我在DIY一个USB手机底座，底座上有3.5寸耳机转接插口 底座USB上用UAC1获取手机音频，现在可以用耳机听音乐了 但是手机插上底座后，如果不插耳机，声音也是传给USB底座了，没法从手机中直接播放 有没有办法做到插上耳机后才让手机把音频数据传过来？ 也就是插上耳机的时候，底座播放；没插耳机的时候就禁用UAC手机自己播放音频？ 目前想到断开USB重连，重新发一个新的Descriptor可以实现，但这样断开重连会打乱其他interface的数据传输。不知道UAC层面是否有方法实现这个功能？

This project looks extremely awesome! I'm curious what the general latency is like with it, and am curious if you've measured it at all. I think it would be a...

Di you think the speed can be increased for 193khz audio?

2ch dac for audio output. 2ch adc for microphone input. or more than 2ch if possible.

Is There any way to upgrade USB Fs to Hs? And to add more than 2 CH i2s output?
