Hi there, I am working on the Auto Answering project. I use an External Modem (COM port) with voice support. I have a problem with playing sound on the phone. I heard my sound file with speaker and this file is Ok, but when i wanna playing this file on the phone with WINMM.DLL ,I hear this sound with weak tone!!! Is there any body can help me ? Thanks,

Either amplify the file ("make the file louder") or try to find out which volume-setting the modem-output uses and increase that programatically. For example: you can set different volumes for files played from CD, files played via line-out, etc. I guess (and thats just a guess) that your speakers have a built-in amplifier (e.g., the speakers have a power-cord and an internal or external transformer) and thus what you hear on the speaker is amplified by the speakers. Thats why it sounds too weak when played unamplified (as it probably is on the phone line).
