it it pretty common, only when turning it on (pre-boot). don't worry too much about it.

  Hi guys, I donno if its relevant here. MY dx90 headphone out is not working right side, line out is fine but i prefer sound from phoneout. Can anyone tell me if there is any way to fix this.
Thank you.

 
 

  What do you want to know? The tabs for the sockets are on the sides where they solder to the board. Your phone socket is on the right in the image and I would touch each of the tabs/contact points with the board with a hot iron to remelt them. They check it with some headphones. Make sure you don't bridge any of the solder to another section of the board. 

 
I've had this exact problem two times already. The first time I sent it to iBasso and they fixed it for free, but then after a year it started failing again. Second time no warranty anymore (although the volunteered to fix it for free except for the shipping cost) so I guess I'll wait to find someone who knows how to solder this.
 
In my case it's not that the right channel doesn't work at all, but at times it does and at times it doesn't. I noticed it depends on whether "lateral" pressure is applied to the jack when plugged into the phone out. This means I can't walk on the street with the iBasso in my pocket because movement of my body will intermittently mute the right channel. I use the line out, not ideal at all, but whatever...
 
Is this a normal thing? I don't think so, or at least, it shouldn't be...

 

[ibzmav]

Got it. Thank you.

how was it? so have you fixed your DX90 yet?

Can be made a custom firmware with lower CPU frequency for dx90? or is there any way to made it?

 

[Jono338]

edit ... sorry meant to quote Alpha Floor ...
 
Exactly the same thing has happened to mine, but it's left channel ... and it applies to both phone out AND line out. bleuugh. I've resurrected my old Cowon J3 - forgot how got it was, despite the storage limits.

Of course. But the stock firmware already have adaptive frequency, which depends on CPU load. So why do you need something else?

 

[vaggbaba]

I think that could save battery power. like we can reduce the max frequency  and leave the adaptation of control frequency as is. 

 

[Lurker0]

  I think that could save battery power.

No. Your logic may work for calculations, but you listen music. If it is enough for real time decoding - the frequency is low anyway. If it is not enough for real time decoding, but you have limited the upper limit, it won't be real time. If you don't listen music - just turn the player off to save power.

 

[vaggbaba]

Ok you have right.
But If there is some way to do It I would like to experiment.
Thank you

Does anyone know where to buy an extended battery cover for the DX50 or DX90? There are pictures floating around on the net and people mentioned taobao but i haven't been able to find it. Price is no object here as I really need this. Would be great if someone could point me in the right direction or might even sell it to me.

@damnitsthatguy

If I'm not totally wrong, the battery used in the DX50 & DX90 is the same as the one that was used in the Samsung Galaxy S3 (not S3 Mini).

 

[damnitsthatguy]

Hi Chris. I am not looking for the batteries, I am looking for a bigger cover that can fit larger batteries without having the need to use the silicon case or other cases.
 
Something like this. https://imgur.com/a/N81SO#280PP4F
 
Trotzdem Danke

Whoopsie, I totally missed that you wrote battery cover. Sorry, my mistake. I have unfortunately no idea where to get one of those and haven't found one on ebay either. Maybe @h1f1add1cted knows where to get one?
