Would the Teac UD-501 be able to play DSD on a Linux machine?

According to the specs, the UD-501 supports DoP (DSD over PCM) -
Product: UD-501 | TEAC
and there are at least two applications for Linux which will play DSD files (.dff or .dsf) and output them as DoP; MPD and HQPlayer.

The only other important point is that the UD-501's USB interface needs to be recognised by the ALSA snd-usb-audio driver as a valid UAC2 device. This has been reported as true and working here -
Teac Reference Line UD-501 USB DAC "DSD"
Later in that forum discussion you will see that DSD files and HQPlayer were involved.

HQPlayer @ 139 for a Linux player app. Can't believe it.

I have no problem with the price considering the long list of features (many of them unique), supported platforms, network playback etc. It is a very specific SW for very small group of users.

When compared with the nonsense called JPlay for 99EUR...

I do have a serious problem with all those rip-off audiophile apps.

That includes JPLAY.

Amarra started at 1500$ not long ago!!! For an app that's very easily outclassed by a slightly optmized Linux setup.

These apps are not doing anything else than that what I've been promoting over here since 2007.

If you like feature lists, then sox, ffmpeg, mplayer etc. can't be beaten.

So. What's the point!?!? Don't tell me you bought that app!?!?


I btw compared JPLAY with my SBTouch setup at a friends place. JPLAY doesn't come close ( in audiophile terms). It's not that bad though.


The main issue still - after all those years - is that not any DAC seems to be able to get rid of upstream issues.


Cheers

I don't. I have a problem with unsupported claims in general but do not care if they come with a price tag or free. It is everyone's choice to pay. But the confusion and myths get spread regardless of the price.

You have been arduously promoting many unproven myths since that time, along with things which actually make sense. Sorry.

E.g. proper DSD support including native DSD volume control?

IMO Miska does not sell any snake oil. He has hands-on experience in audio DSP and his SW is basically a player with advanced efficient DSP. His computeraudiophile posts do not spread audiophile myths.

I do not need the features of his player, I have no DSD tracks. Plus I like to tinker with my system and his SW if closed-source. But most people have other hobbies

Comparing JPLAY with SBTouch when both run on different HW? So what did you actually compare?

JPlay is a scam. But the technically questionable mods of your SB Touch toolkit were never confirmed to work by a blind listening test either. In fact I have read numerous reports with conflicting results.

IMO the main issue is the lack of transparent and objective tests. Only these would show the scope of reality and believing.

If you'd ever make it into my region, you're invited.

And.

There'll always be different messages out there. They do cause conflicts
because certain people don't even try to understand, why these messages are different. Usually it's the lack of knowledge causing those conflicts.

People and systems are different.

I have no problem with people who do not hear any differences. There's an explanation to everything.

I just had such an experience myself when comparing Toslink cables.

On my system I couldn't hardly distinguish two different cables. On a friends system who's running ETON ER4 AMT tweeters the difference between those were day and night. I'll be trying AMTs in my system soon.


Bottom line. The most imortant thing is that you stay openminded.
I can easily accept that you don't hear differences. You're a hacker.
You've got different priorities.


BTW: MPD plays DSD. No reason to go for a 129 product. Combine MPD with sox and you'll be set.

Ubuntu Studio 12 + Emu1820m + Reaper + Wine... Works... or Alsa + Jack + Ardour... Works too. Recording 24 bits and playing 16 bits.

I am looking to schematics to 1820M (rear line inputs).

Thanks, the same for you. And if you like beer...

How many times have I heard this argument when asking posters to verify their technically-unlikely claims (both commercial as well as non-commercial) with blind listening tests? No, this is just a straw man. Either present objective results, or accompany your claims with subjectivity qualifiers ("IMO", "I hear",etc.).

I have absolutely no stakes in HQPlayer but MPD cannot upconvert DSD nor change DSD volume natively. Yet. Not that I would need such features but that SW does offer something for its price not available in free projects.

Default TEAC UD-501

I wanted to report in on the TEAC UD-501.

I just got this unit to test it out with Linux and MPD. I have been using MPD for years and really love the audio listening paradigm it supports.

In short, this DAC seems to have some problems with USB and Linux. You can get it to play out of the box, but (on pcm) when you change sampling frequencies it borks up and has to be stopped/started again. As for DSD there is a loud pop at the beginning of each track, you can also avoid this by stopping/starting (Stop the last track before it ends then start the next track... quite manual).

I'm posting to hear from anyone who might have experienced this and found a fix for their issues. Here is a gist with some of by information for debugging purposes:
