DAC-X7 XMOS XS1-L1

Postby Gregzila » Tue Jul 30, 2019 1:49 pm

Hello,

We have a question about a xmos products DAC-X7 Fx-Audio With Chip XMOS XS1-L1
I think that the XMOS chip goes to sleep when it no longer receives audio signal, there is no sound for a second while the chip wakes from its sleep mode
Is there way by a firmware flash to cancel this sleep mode?

Thanks in advance

Hello,

I try on 3 PC
1 on windows 10
1 on windows 7
1 on Ubuntu

I try with different drivers Thesycon 4.47 or other driver Microsoft 10.0.17763.1

And I'm not the only one with this problem :
Here :
viewtopic.php?t=1596
1. If I start to play some audio I have a long delay till I hear the sound. It can last up to 1 second till I hear the sound. I have tried an other DAC (PCM5102 in parallel on the same I2S interface) and there is no delay!
or here :

Only bad thing is the delay of signal 1 sec delay, which gets me mad some time.

But there is no answer?
Please help me

Hi.

1) Have you attempted to contact the manufacturer of the DAC-X7 Fx-Audio product? What are their comments on this issue?

2) In assisting some other customers and developers of similar hardware, some of these products should not be shipping. Without a doubt the engineers have not done their homework and end customers are swearing at how poor quality the product is or incompatible with the shipped device drivers and worse yet, the product is dead after a few power up cycles. That is pure garbage for an end user experience.

Voice your complaints to the manufacturer and demand your money back if not satisfied.

To further complicate this and most other cases, you are going down a rabbit hole to h*ll with the investigation. Many of these "custom" boxes are invoking a custom boot loader that encrypts the audio IP. Even if you could reflash the firmware, you are stuck to the encrypted firmware that only the original "designer" can support. This is from experience in trying to assist another user of XMOS products who has a pile of defects from supposedly a well known audio company. Reached out to them to assist (no charge) and they would not come on the phone.

My comments...Lump it and continue to sell your garbage!!
