我正在使用OPPO FindX5 pro(带3个MIC(录制系统音频，我指的是tinycap。但是，我无法通过它进行记录。
步骤1:我检查了声卡
OP5209L1:/proc/asound # cat cards
0 [waipiomtpsndcar]: waipio-mtp-snd- - waipio-mtp-snd-card
waipio-mtp-snd-card
步骤2：我检查哪些设备可以用来记录，在那里我们观察到"；6-11/14 16 18 20 21 22 24 26 28〃；具有捕获能力。

第三步：我试着录声音，但它只是警告"捕获的0帧"；。也许我错过了配置tinymix？

但是我如何配置tinymix，有很多选项？
