Have you ever noticed the different pronounciation from some people?
I'm not sure if this is commonly done in other parts of Sindh, but In my area, some of people replace the ڇ with ش, in many words like saying شا instead of ڇا or like مشي instead of مڇي,
I dont know why some people pronounce it like that, But have you ever seen people speaking Sindhi like that? Let me know
