USB Audio on a Boombox
Getting USB audio working on a Sony ZS-RS60BT
In an earlier post, I got USB audio working on my used, manual, 2013 Honda Civic EX. Today I’ll do the same for a Sony ZS-RS60BT boombox.
 |
| Here it is in all its used glory after a little cleaning. |
Background:
I decided I should get a small portable boombox to practice my dope dance moves. I currently still suck because I think I spend more time computering than out on the floor. In any case, in a stroke of luck, I happened upon a used boombox that was getting discarded due to a broken CD player. Nobody seemed either able or interested in getting USB audio working, so I took it home and gave it a go!
Initial attempts:
Some initial attempts at formatting the USB key ended up with this:
 |
| The device printing a NO DEV message. |
Others got it showing a marquee message of “NOT SUPPORT”.
 |
| NOT! |
 |
| ... NOT SUPPORT |
Hmmm, I guess we have to go really old school here.
Identification:
The code inside this thing must be really old. So after some digging, I found out the magic incantation. The device expects a drive with a single partition, labelled in a magic way.
My usb drive was /dev/sdb. You can find this out by watching dmesg --follow
when you put it in…

I popped open fdisk next. You can use p to print the current state. You can
type m for the menu. You’ll want to use n to make a new partition, then use
all the defaults. After that you’ll need to change the partition type with t.
The code we want is W95 FAT32 which is represented by a b. Select that and
then exit with w to write everything to disk. My logs of this are included:
james@computer:~$ sudo fdisk /dev/sdb

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Calling ioctl() to re-read partition table.
Syncing disks.Filesystem:
Finally, let’s build a filesystem.
# mkfs.vfat -F 32 -n BREAKBEATS /dev/sdb1
mkfs.fat 4.1 (2017-01-24)Make sure that your label is all UPPERCASE if you decide to use one. After this I mounted the partition, and copied over some non-copyrighted mp3’s to it. It will even read into nested folders.
You might want to consider using fatsort -n /dev/sdb1 if you want to get
things playing in their desired filesystem order. I explained this in my earlier
car audio article. For this
use-case, I didn’t bother to because all my break beats are random tracks that
don’t have a particular album order anyways!

Battery life:
When plugged-in or running off of batteries, there is a small amount of phantom draw, so I take out one battery when it’s not in use. (The 6x1.5V C cell’s are in series, so you can remove any of them to disconnect the circuit.)
Conclusion:
As a bonus, it even comes with a storage drawer for your AUX cable and extra USB drives!

| Store some stuff here if you don't care about breaking the CD player! |
And here’s one last thing to make you all jealous… My machine’s volume can go up to eleven.

| Up to eleven! |
If anyone in the Montreal area wants to break/pop with me, please say hi.
Happy Hacking,
