No.

But, see how DDDAC works; its "motherboard" does exactly what you need.

Hehe, That's what I thought.

I'll have a look at DDDAC but assume it comes with a load of functionality I can't use.

As Nick said, WaveIO is USB to I2S / SPDIF only. No I2S to I2S or something like that! Even though I like Doede's approach on muxing I@S signals using logic gates, my advice is to use relays instead even though, both of the paths are requiring a bit of care in building them properly.

I'm still a little confused on the driver situation. My wife got me a WaveIO board as a gift back in February, 2016. I've actually not used it until now. I don't think I ever got the driver (or if I did, I've since lost it).

Anyway, fast-forward to today. I'm using Windows 10 and the WaveIO board "just worked". Looks like, as DimDim suggested, it's the Microsoft-provided USB2 driver. ASIO also appears to work via ASIO4ALL v2 and the ASIO output in Foobar2000. I did have to pretty much max out the "Buffer Offset" ASIO4ALL setting to fix some crackling/static.

Is there any advantage to an actual XMOS or Thesycon driver?

Also, if I understand correctly, all this driver complexity goes away under Linux, correct?

Hello Matt,
I already emailed you so I hope you have the driver already! As the one tied to your order back in February 2016, I'm sure it was sourced since it's part of my standard procedure. Either way, every time you need the driver just let me know and I'll send it to you again.
Thesycon drivers: I'm fully thrust in their work. In fact, I never had any complains in 7 years of using them. As for Microsoft, my PC forced the 1803 update the other days and I already spent one week to "reverse it" back to 1709 and stay there due to various errors I encounter with 1803. Should I say more?
Linux: no driver needed!


Kind regards,
L

can anybody share an Xmos Driver for the Breeze DU-U8, one where you are able to modify the latency and buffer ?

Default Getting the WaveIO to max out with a DDDAC1543...

Hi all,
Had Lucian's WaveIO board for almost two years, and just got around to fixing the issue of supplying the isolators on output, which I didn't figure at first glance. This was intended to replace the original USB receiver in my DDDAC1543, which turned the corner a while back. It successfully just did.

In any case, skip forward to the issue at stake here - I am trying to make some sense of the possible formats that can be played in this combination. Tried a bunch of different things, from misc. online streams of some varied bitrates, all the way to Tidal in hifi, and even tried some DSD files (which, to my surprise, I seem to be able to play though this combo). Any such renders either 44.1k, or 48k, read via TUSBAudio Control Panel, which was installed by WaveIO's driver.
I also have a Fiio Q1 MKII - which has a weirdly similar driver, btw - and this other guy plays a variety of formats, as expected.

Is it:
- inherent limitations imposed by the DAC (TDA1543)?
- the player? (I can't figure out making Foobar reliably work with the WaveIO)
- obsolete driver (I'm having a bit of a hard time getting a hold of Lucian at the moment, so my driver is a 2016 version).

Thank you all for your help with this.
Radu.

P.S. Nah, I am not sure DSD formats go through this... Just re-checked my players.

Maybe I'm being dumb but I'm not clear what your problem is. Have you got your WaveIO driving the TDA1543 DAC with normal PCM data? It's been a while since I used my TDA1543-based DDDAC but AFAIK the chip works with PCM data only.

What seems not to be widely appreciated is that, despite its age, the TDA1543 can handle PCM data rates up to 192 KHz - see the datasheet and ebay adverts for apparently excellent Chinese products that use it.

The oft-quoted 48 KHz limit was down to the limitations of the USB>I2S boards of the time when the 1543 was more widely used. So, if I have you right, the answer is PCM only but up to 192 KHz. Perhaps I should try mine out again . . .

HTH

Hi Dave,
No, I think you're right on the money here. To exemplify - I am running this moment a FLAC file at 352k/24bits and I see the WaveIO control panel showing the current sample rate at 48kHz?...
I assume the 16 bits limitation of the chip stays in place and will apply to any incoming signal.
