Thank you iori

I use mqndevinfo>>mqnparam.txt to retrieve my dac info.
No sound, no exception...

If you have more than one USB sound device connected, remove them all except the one you want the USB deviceID of.
I had multiple connected and I got the wrong one each time until I removed the rest.

Hi Aleg,

The device id is the same I hardcoded to mqnplay ldn v15 and it works fine. Besides, I have only the Hugo audio usb device connected.

here's mine

\\?\usb#vid_1852&pid_7022&mi_01#6&851d114&0&0001#{6994ad04-93ef-11d0-a3cc-00a0c9223196}\global

ldn one would have extra \\ eg \\\\?\\usb

latest versions don't have hardcoded c:\musicplayer

might try

start MQncontrol --file ".\Files.txt"

to

start MQncontrol --file "d:\test\Files.txt"

in mqn.bat

ldn one would have extra \\ eg \\\\?\\usb

Mine is:

Just for the sake of it, tried doubling the back slash and still no sound.

passed the play loop through an intel analyser and it identified one issue so tried to fix it.

uploaded play haswell v38, a bit more detail and lighter on it's toes than v36, so maybe there was something to it.

v38 looks like

Hi elaprince,
just checked, all ver. from 2013 to May 2015 can be played in any folder other than C:\musicplayer.

iori

[Aleg]

...

latest versions don't have hardcoded c:\musicplayer

...

I had missed that change.

It will make it easier to do version comparissons again.

Thanks

Cheers

I downloaded all the required files again from the MQn site and v34 is playing fine.
Downloaded mqnplay v38/control and load v25 and like it a lot.

[sbgk]

shaved 2 uops off

uploaded play v39 haswell, a bit special this one, maybe a good place to stop sq mods.

[elaprince]

iori thank you for replying
No it doesnt play
I have try many different way editing MQN.bat and still no luck
Gordon can you double check it that latest versions are not hardcoded please?
Thank yuo

Iori can post or pm your bat modified to play from D: ?
Thanks
