I can play DSD ISOs, but only in redbook

Hi, I'm just starting my trial period with JRiver 21, Ubuntu 14.04.3, 64 bit on Intel platform. I'm using an SMSL M8 DAC via USB. SACD ISOs play, but only at 44.1 mhz. If I go into "DSP studio" and select "DSD in DoP format", I get soft white noise. With the other DSD options, I get an error suggesting unsupported hardware or other issues.  I hope I can clear this up!!

Edit: So far, I can't play PCM above 48 khz. 96khz is playing at 48khz. Redbook PCM plays at the expected 44.1.  I can get up to 384khz with other software.

bamyasi:
Really?!?

Nobody has any suggestions even for the PCM bitrate ceiling I seem to be hitting? I can play 24/96-192 and beyond no problem with other linux players.

(In output format) > Sample Rate :

This is the mapping of input sample rates to output sample rates.  Look at (for example) 96kHz and see what it's output is set to.  If you want no conversion for some sample rates (say up to 192,000), then set each of them to "no change".  For those that you do want changed, choose an output format that your DAC can play natively.

In Output Format > Output Encoding, you should probably leave this set to None.  This is used to convert *everything* to DSD or Dolby Digital.  You probably don't want to do that.

Thanks for the reply!!

I have all the PCM rates in DSP Studio set to "no change" up to 384khz, the upper limit for my DAC. According to my DAC, nothing is playing over 48khz, including 96khz and 192khz files. All DSD material will only play at 44.1khz.

Audio Device is set to Default [alsa] and device settings to "auto"

I don't have any experience with Linux sound devices and MC.  Maybe someone else can comment.
