Sorun, pyaudio'nun bir sürümüne özgü gibi görünüyor, bu nedenle güncelleştirmeye çalışıyorum. Ben pyaudio güncelleştirmeye çalıştığınızda : Bu mesajlardan

Yok fiili hatalardır. PortAudio, olası tüm ana makine API'lerini ve cihazlarını "ping" eder ve kullanılabilir olup olmadıklarına bakar. Bu genellikle terminalde, çoğu durumda göz ardı edilebilecek birkaç mesaja yol açar.

Bu iletileri basmayan bir Python PortAudio sarıcısı istiyorsanız (bunları sizin için bastırdığı için), sounddevice modülünü gözden geçirin.
