Phil Williams Posted September 28, 2019 Posted September 28, 2019 Hi, I've just setup my media PC to play via coaxial. I have two outputs one from motherboard one from auxen 7.1 soundcard. When opening jriver or tidal a get a high pitch squelch noise. The DAC in my preamp actually Just plays pure noise all the time from the motherboard output so I don't use it. The coaxial from sound card plays to the preamp DAC no noise, but the coaxial soundcard to my Melior DAC (beautiful sound) plays a squelch which stops once music actually is playing. Sometimes I hear the squelch repeat but get quiet over 5 seconds. Any ideas please?
Guest Muon N' Posted September 28, 2019 Posted September 28, 2019 So you have a Pre Amp with built in DAC, and a separate DAC ( Melior ), motherboard sound and a separate audio card being the Auxen? I'm likely of no help, but if clearer someone else maybe able to help.
Phil Williams Posted September 29, 2019 Author Posted September 29, 2019 Yes, that's right, motherboard and sound card coaxial spdif output options. motherboard output is just digital noise, can't use, sound card output fine, but with startup squelch. I wonder if there's a option in media centre/ windows that can affect. Most settings I have enable player to take control of volume and exclusive right.
Gordon Macfarlane Posted September 29, 2019 Posted September 29, 2019 (edited) What software are you using for replay? Do any of your dacs have a usb input as this is likely to sound better than spdif from a pc in most cases ,as I understand it? Edit : Just checked on the Melior dac and see that it doesn't have a usb input. There could be so many reasons for the problem but have you tried different play back software ? Also download the free version of Fidelizer , it won't solve the problem but it will certainly help with sound quality based on my experience( it is not snake oil by the way Edited September 29, 2019 by Ozcall
Phil Williams Posted September 29, 2019 Author Posted September 29, 2019 Using J River. Will try recommendation. For a DAC spdif convertor plus USB cleaner I'm thinking I should just buy a audio PC? Any reviews recommended?
Guest Muon N' Posted September 29, 2019 Posted September 29, 2019 IF you are using windows also try Foobar 2000 for playback, a very good free program. Of course go the stable version https://www.foobar2000.org/

I use Jriver as well but without the problems you are having.Unfortunately I don't have the depth of knowledge of the programs audio settings to guide you to solution. I experimented with the Singxer F1 usb to spdif card. I found the sound quality from spdif into the dac to be poor until I removed the spdif cable and replaced it with a male to male rca coupler I got from Jaycar. Effectively the usb board plugged diredtly into the spdif socket on the dac . This actually worked surprisingly well. I am busy working on a Raspberry pi based music server and even with a very basic setup the results are promising. Happy to share the info if you are interested.

Or does this "squelch" occur just as music playback starts but then stops some time afterwards?
aussievintage Posted September 30, 2019 Posted September 30, 2019 I am wondering what the OP means by squelch. Squelch is not a noise. It is the muting of audio in the absence of a strong enough signal. 1
kukynas Posted September 30, 2019 Posted September 30, 2019 make sure you set your output device in Jriver properly and that you have installed your soundcard drivers Tools > Options > Audio > Audio Device
Phil Williams Posted October 7, 2019 Author Posted October 7, 2019 Thanks to all who responded. The noise emitted is high pitch, digital in character and likened to a radio squelch, iT happens whenever I load a program that has audio. J River was the worst, and I actually had delay in playback. Jriver now set back to default, will send screen shot. Interesting that when flicking between source in PC and audio is playing the noise dosent happen, to me it sounds like the PC engages the audio card, and this sends a signal the DAC is picking up, which it should really ignore.
Phil Williams Posted October 7, 2019 Author Posted October 7, 2019 Adding J River settings. Sometimes when starting teacks J River appears to play some seconds of music over a longer time than one second. Odd ...

This sort of shite is why I prefer analgue Seriously, it sounds like either the sound card driver, or the soundcard firmware/hardware, or the noisy DAC, is not doing what it should. I would probably try a totally different soundcard. Even if the DAC is the problem, a better interface may resolve it. An earlier point where you said another DAC just plays continuous noise may in fact be related to the issue.
Phil Williams Posted October 7, 2019 Author Posted October 7, 2019 Thanks, I do have a PF800 for those days...
Guest Muon N' Posted October 7, 2019 Posted October 7, 2019 (edited) If you just use the add in sound card, have you tried disabling the on board sound in device manager and uninstalling It's drivers/software. Or do you need both for some reason? Edit: my train of thought here is a device/driver conflict between the two audio devices. Edited October 8, 2019 by Muon N'

You're not using a direct connection here so the Windows sound system (Direct Sound) will make some changes. Albeit probably small and inaudible but you're not getting bit perfect playback. If you use WASAPI (Exclusive mode) or ASIO then JRiver can provide bit perfect by having exclusive usage of your sound card / device. What I'm suggesting may not fix your problem and it might actually make it worse but you might as well setup JRiver optimally and try it. Edited October 8, 2019 by Satanica 1

No shite with analogue except ,vta ,azimuth ,cartridge loading , support structure .........
