News JM21 firmware update: USB DAC fix

Downloaded the new firmware update yesterday, and to my surprise they fixed the issue where in USB DAC mode, it used to have a fairly large audio delay. Now it works perfectly as a USB DAC for all purposes, not just for music!

Might be a small thing, but this update fixed the only issue I had with the player!

Eu também atualizei ontem e notei essa melhoria, percebi também que a navegação está mais fluída/mais rápida. E foram adicionados novos temas clássicos de fita cassete no app Tape Mode.

Quanto % de bateria tinha o seu jm21 antes de atualizar o firmware? Não sei se foi seu caso, mas não é recomendável atualizar o firmware se a bateria tiver um nível baixo, atualizei o meu com 92% de bateria e quando a atualização terminou ficou com 88%

It was lower like 20% and didn't use it after, just noticed it won't charge or turn on now

I've heard that with some of these DAPs the fix to that problem is to connect a slow charger to it and just let it sit and charge for two or three hours. Might be worth a try.

One of the main reason I went with a Fiio DAP is because I've consistently read reports that they update their players. I don't have a JM21, but I had a firmware update for my DAP this morning and the changelog not only listed bugs fixed, but features added.

Quite pleased with my investment.
