Here's a GREAT idea! BECAUSE this is such a nice but older Sony... "I" would use a Blu-Tooth SPEAKER with a AUX speaker input! LOTS of AUDIO and VERY inexpensive too!

OR I recently bought a BlueTooth TRANSMITTER/RECEIVER that has a 3.5mm" Jack right from it's body! Depending on the 'mode' it's in ~ it will TRANSMIT audio (like from your Sony) to a Bluetooth Speaker! (In it's second mode it acts like a BT RECEIVER.)

Here's a official title of another:
Mini Bluetooth 3.5mm Music Audio AUX Wireless Transmitter eBay: 322589063752 and it's about $7!
This puppy is a Bluetooth TRANSMITTER only.

"This device can transmit music from your media devices(smart phone, iPad, mp3, CD/DVD player , TVs and more) to your Bluetooth-enabled equipment (bluetooth speakers/Bluetooth headphone, etc) simultaneously"

THEN there are THESE "3 Watt" BLUETOOTH RECEIVERS for UNDER $2 ! I KNOW! Hey man ~ just pick your color!

eBay: 112673621308 DANG ~ I'm going to order some now!

MMMmmm try earphones? How is the volume then? Plenty?

ALSO earphone jacks become dirty and the contacts that SWITCH THE SPEAKER OFF become poor conductors that starve the speaker for volume... anything more than this MAY constitute a MAJOR repair cost...

SO KEEP your SONY and consider the options!

You an inline battery powered signal booster, they are cheap.

Look for a program called Sound Booster or one called DFX. DFX is my favorite because it not only boosts the volume, but lets you add other effects to enhance you sound as well. There is a free version. but to get all the effects you have to upgrade to the paid. If audio is important to you, check it out.

Turn up the volume on your iPhone. Also, try connecting your iPhone or any other media player, e.g. computer, to the AUX IN jack on the speaker and see if the volume is higher for that connection.

try turning the volume up. My iPad mini seems to have a lower volume level than my iPhones. The external speakers are almost inaudible unless turned way up, so I mostly use ear buds on it. But be careful using the earbuds! turn the volume down and gradually increase to a comfortable level,

There are several issues that may be causing the volume to be very low.

SPEAKER VOLUME:
(1) When you press the Vol+ button on the speaker does it make a beep sound? (It should, even if it can not longer go up or lower).
(2) Be sure to continue pressing the Vol+ Button to ensure that the volume does increase.
(3) While this is rarely an issue, may want to check that the speaker is charged.

DEVICE VOLUME:
*Please note that some devices have a separate volume control aside from a blue tooth devices volume adjustment.
(1) Ensure that Media Volume is on.
(2) Ensure that the volume is turned up on the device by using the devices Vol+ controls

MEDIA VOLUME:
*Please also note that the media being used (Youtube, Hulu, Music Player, etc.) may ALSO have a separate volume control aside from a blue tooth devices volume adjustment.
(1) Check that the volume within the media is turned up as well.

Disconnect it then reconnect it

Check your menu on the Samsung to switch audio out selector. You might have to use ANALOG outputs instead.
you could then eliminate digital to analog adapter.
Analog out uses the RCA PLUGS.

The iPhone detects when earphones are plugged in, and deals with volume differently as your speaker volume may be inappropriate for the use with earphones. Bluetooth is managed with the same volume level as earphones. Once it is disconnected manually adjust the volume with the volume buttons or check if your silencer button is not activated. Hope this helps!
