遊戲沒聲音

[plush sleet]

在遊戲中沒有音樂和音效，確定設定有開

Dumb question but is your phone muted

[plush sleet]

沒開靜音

[wanton pulsar]

居然是中文(虽然是繁体)

[iron bone]

I don't know why you use Chinese, when the rules clearly state that English should be used

In any case, if there are audio problems, clearing the game cache may solve the issue
