你嘗試把你個speaker拿去另一部機聽吓得唔得,如果都唔得就是你個speaker壞左,建議你拿另一個speaker試吓
如果你個speaker有聲就是你本身電腦問題(軟件或硬件),在軟件方面 -- 建議你upgrade你的喇叭程式. 硬件方面 -- It may be a problem of Sound Card (sound card may be a seperate card or on-board). If it a seperate Sound Card, you can replace it (by using another card or buy a external USB sound and speaker card at around HK$40) and try again. If it is an on-board Sound Card, you can also use an external USB sound and speaker card and try again. I have faced this problem previously and it is workable. Thank you and hope this can help.
