Cd/dvd alpine stereo no sound cd reads

Just a thought - the usb provides a digital signal which carries information about how the signal is to be processed; mono, stereo, surround sound stereo, etc.
If the mp3 music file was only recorded in 2 speaker stereo perhaps that is how it plays back.

Admittedly the radio signal is stereo and yet it plays on four speakers but unless it is a DAB radio it is analogue and maybe that makes a difference.

Perhaps there is an internal electronic fault with the digital processing part of the unit. I suggest reading the handbook again and then perhaps contacting the seller.

are the cds you are using copys or originals as sometimes the copy wont give you the stereo sound that you want but if you are getting stereo sound through the radio and all speakers are working there should be no reason why you dont get sound through all 4 speaker through the cd as they all go through the same channels and produce sound the same way as the radio the only problem i ever had with sound was that the copys wouldnt give me stereo sound but the only other problem could be is that the cd player in the unit is damaged or something come loose on the actuall cd unit in the player itself have you tried ajusting the loudness of each speaker and see if their is any sound at all if not and you are using originall cds then their should be no problem with the sound you could try turning the stereo sound off and have it on mono then see if you get any sound in the other speakers if not then it is fault with the unit itself this can be difficult to repair and expensive to get parts for how old is unit try playing round with the speaker volumes if this dont change anything and the mono and stereo sound dont change anything then it will need to be repaired so i would sugest to take this to repair shop as this would be difficult to repair hope this is some help to you ........................................

Its trouble is in inside

Please check carefully the format the CD you burn. Your player should has at least same format or better to make it read the CDs.
For example standard dvd player will not able to read mpeg 4 CDs.

hello sir hi, If the CD is playing, but is no sound coming out from the player, this may be the likely trouble. sorry there are no quick fix for this.

• check for selector switch contact, a faulty switch with poor contact does not connect the correct circuit where the signal of the CD should go to be amplified.
• dirty or loose CD lens contact, a visual circuit inspection is needed here.
• signal break from the CD lens to the power amplifier is needed to be checked, this requires to be checked by a technician with an oscilloscope to trace where the signal got lost. this is the best way to find the trouble.
• The spindle is not spinning or spinning fast to properly read the disk. OR
• Bring it to a Car stereo dealer and ask for service. They have in-house tech guys to analyse the trouble.

If the price of service is higher or very close to a new one, i guess its time to buy one.

If the sound is coming out clearly with the radio on, then there is a problem with the cd drive or its connections. If your stereo has aux. inputs, you could run an mp3 player until your ready to replace it.

read the manuel

See page 13 in the manual and make sure BBE is the same across all modes (sources)

I didnt think alpines had codes?

are you sure it has one?

sounds more like a connection problem

Disconnect the blue wire from the back of the radio and connect the blue/white wire in its place. This should fix your problem.
