Hi, I have similar issue as in thread https://yabb.jriver.com/interact/index.php?topic=111435.0
Message "Playback could not be started on the output 'ALSA' ... ' apears when DSDx4 is chosen in DSP studio.
Chosen device is plughw: CARD = audio, DEV=0 [ALSA] McIntosh HD USB Audio, USB audio. Hardware device with all software conversions
I'm using the newest Linux Mint 20.
I've updated limits.conf [attachment] file but still I have issue with upsampling to DSDx4
DSD is working fine (Bitstreaming = Yes (DSD))
What else I can do?
-
Don't use plughw.
Use the hardware device, hw:whatever.
In the Audio device options check the native dsd box if your device supports it.

thx, I tried:
hw: CARD = audio, DEV=0 [ALSA] McIntosh HD USB Audio, USB audio. Hardware device without any conversions
front: CARD = audio, DEV=0 [ALSA] McIntosh HD USB Audio, USB audio. Front speakers
result was the same.
When I have output DSD files in native DSD format checked and Bitstreaming = Yes (DSD) then I have message "Playback could not be started on the output 'ALSA' ... "
I used only native DSD format checked. When I was playing DSD (ISO or .dsf) DAC was presenting 352,8 kHz. As well when I was using DSP and upsampling DSDx4 I received the same message about "Playback could not be started on the output 'ALSA' ... "
EDIT:
W PCM audio format is available:
- auto
- s32_le
- s24_3le
- s24_le
- s16_le
is it ok?
-
go to a terminal window and run
/usr/lib/jriver/Media\ Center\ 26/alsacap
and attach the results please.

sure

It doesn't support native DSD so you can uncheck that in the Audio->Device options.
You can try DSD bitstreaming under Audio->settings.
That will DoP but that doesn't often go up to x4
-
Ok, DOP in DSP studio works fine. Thx
I assume that my DAC hasn't support for native DSD added to ALSA and/or the Linux kernel itself :/
