Hi everyone, I have a problem with x86 volumio version. When I switch from a Flac to a DSD a pink noise comes out and I am forced to stop playback and then restart it. Sometimes it works but not always. It is impossible to create a playlist with mixed files because it freezes and makes noise, what can I do?

Hi,
Sorry I couldn’t find it on your log - what DAC are you using for playback?

You get noise with DSD if the volume is less than max.
Dac is integrated in my amplifier, volumio report this model: SXW CTUAD768 PRM-A
in setting volume is on max value.
This section is my Dac

I think is the same problem in this page:
Volumio 3.785 (RPi 4) + Emotiva XDA-3 no native DSD (DSD via DoP only).
Is there any solution to this problem?
ASIO driver or additional software support required?
Hi.
Ok, so your amp is an Emotiova XDA-3, which has an ESS ES9038Q2M SABRE DAC and uses a ComTrue CT7601 chip interface (SXW CTUAD768 PRM-A according to the manual (Xda-3 Rear Panel - Emotiva Differential Reference XDA-3 User Manual [Page 15] | ManualsLib ).
From the link you provided (Volumio + Emotiva XDA-3 no native DSD (DSD via DoP only) ) , it looks like you’ve already identified where the issue is, which seems to be in the firmware implementation on Emotiva’s side.
It is not a dac chip issue - I’ve run the same chip in native I2S hats and XMOS chips with no issue when playing native DSD or DSD over PCM. And the same with the ESS9039Q2M. Hopefully they get around to fix this soon!
Hi,@mastri81 has the same issue as me, and he doesn’t have an Emotiva XDA-3.
It is therefore possible to conclude that the trouble lies in Volumio’s (actually Linux) inadequate interaction with DACs based on the ESS ES9038 SABRE and ComTrue CT7601 USB interface in general.

Guys trust me, the issue is related to the CT7601 firmware or in the register settings applied to the ES9038 DAC.
I have here on my desk this very same combination, with both CT7601 firmware and ES9038 registers developed and fine-tuned by myself. I have absolutely no problems with DSD playback and DSD ↔ PCM switch, with default Volumio settings.

I can also confirm no issues with the ES9038Q2M in other implementations using both native i2s interfaces and XMOS chips on my end, so everything does seem to point to this being a specific issue with the ComTrue CT601 / ES9038Q2M implementation cited.
Hi Darmur,
I am 101% convinced that you know what you are saying and that you have checked it out.@mastri81 and myself deal with this?
Yes, I have also checked other DACs with XMOS. Everything worked without a problem.DA-400 - TAGA Harmony was on XMOS.

the most obvious solution is to contact the manufacturer of the DAC, explaining the problem in details and asking for a fix with a firmware update.
I agree that it seems to be a specific issue affecting devices that use certain Comtrue USB interface chips. However apparently those devices work normally with other sources.
To me this suggests that the source is “recognizing that it is talking to a Comtrue chip rather than some other specific chip or an unknown generic UAC2 device” and then implementing some sort of extra actions. To me this points to some “special handling” that is being done at the Linux kernel driver level only when it detects a Comtrue chip in the receiving device - and that, in this case, has undesirable results. (And the solution would be to have the option to disable this “special behavior” in the Linux internal driver.)
Incidentally, I work for Emotiva, and I can tell you that the XDA-3 was originally tested successfully with both DoP and “native DSD” - using Foobar2000 in Windows 10 - with no such issues noted.

Hi, and thanks for chiming in - I appreciate the fast response times and dedication at Emotiva! Part of the issue here is that there appear to be devices or set-ups running the same ComTrue + ESS ES9038Q2M configuration that are working correctly. And, out of curiosity regarding device compatibility, would it help to test the device with macOS, iOS, Linux, and Android as well?
On Android 14 whit Neutron Player no issue.

On PiCore player, MoOde and Audirvana linux core - problems.
Thanks for this! I wonder what the device is using - ALSA, OSS, or something custom (by the Neutron engine).
Interesting - maybe BluOS is also using ALSA?
I don’t exactly disagree with you… The problem is that there are a lot of different Linux distributions - and each does or may act differently in different ways. So testing a product with one Linux distro provides little assurance of how it will act with others. And, for that matter, there are a lot of products that simply use proprietary distros or hardware altogether. Emotiva is primarily an audio company - so the USB interface part of the XDA-3 was developed for us by an outside engineering team. When we received the prototype, we tested it with both Windows and Apple devices, as well as with a few Android devices, and it worked fine with all of them. It is also, as far as we are able to determine, compliant with the USB Audio Class 2 standard.
In this case it appears as if the issues some people are experiencing with some devices are due to certain Linux-based devices accessing certain features or capabilities of the Comtrue chip which we don’t use… and which extend beyond the standard. Likewise, we process DoP packets as per the standard… so we assume that the drivers inside a particular Linux distro are encapsulating the DSD audio into “standard DoP packets”… and we handle those as per the standard as well. Unfortunately we lack the resources to test each of our products with every other product out there… or to work with individual vendors to optimize our products to work with theirs… so we follow the standards and assume that other products do as well. (And we offer a return period to protect customers against the unlikely situation where one of our products has any sort of “compatibility issues” with other products in their system.)
As it turns out we are in the final stages of releasing a new streamer product, which we developed in conjunction with Volumio, and which runs the Volumio operating system. Our new streamer has its own internal high-quality DACs, so I doubt many folks will be using it with an XDA-3, but we will test how well they work together, and report the results.
(You will usually find discussions about Emotiva products, including the XDA-3, in the Emotiva Forums… and, since we’re developing the new streamer with Volumio, probably here as well. )
