I mean that, over USB, PCM operates up to 192 KHz (Squeezebox maximum)
and DSD is detected correctly by the DAC and plays as native DSD. 
Sounds nice too!

Re: [SlimDevices: Beta] LMS 7.9 and DSD

Well I seem to h ave accidentally solved the issues I was having.  It
had been my intention to upgrade my DAC, so I purchased a SMSL M8A. 
When I connected it, my attempts to play DSD, both natively and via DoP,
met with failure but the nature of the failure was the clue.  The DAC
kept switching between PCM and DSD and operating in 'bursts'.  So

Switching from wireless to a wired connection fixed it completely.  All
is now working as it should.

Thanks for a the advice and support!

I will try this.  I had formed an obviously wrong view that playing DSD
was dependent on using USB connection.  I'll post results.

Thanks.

Re: [SlimDevices: Beta] LMS 7.9 and DSD

Hi

Please forgive a very n00b question.

I am trying out DSD on LMS 7.9 and SB Touch with an external DacMagic
DAC (quite elderly and pre-DSD).

I am able to get my DSF files playing without a problem (EDO, USB) but I
don't understand what is happening 'under the covers'.  The state of the
'Enable DSD-over PCM' option makes no difference to the sound output and
the DAC shows 44.1 sample rate at all times.  Is this correct?  Will a
great deal of resolution not be lost at this low sample rate?

If you can aid my understanding or point me to a learning resource, I
would be very grateful.

TIA
