Issue with Cayin device, speed and buffer jump

[Robert_F]

Hi everyone,

Just took my license for origin since it’s seems to be the best mac decoder.

Yet I’m getting hit with continuous problems…

• Scan is very slow and inconsistent, items are missing
• When mounted with my Cayin DAP it plays at 5x time then buffer, etc so unusable
• It switch between two track every 5 secs. Play the first, move to next, back to first.

I though that it was a mature app but those are frustrating and make the app impossible to use.

Is there some corrections deployed, am I the only one with such experience?

Thanks,
Robert

Hi @Robert_F,

Sorry you experienced such issues. I will help you for them

Can you send us a copy of the “Debug Info” when you have this issue? You can get it in Audirvana Settings>My account

Note: By clicking on the Debug Info button, Audirvana automatically copies all its content, all you have to do is paste it in response to this message

Hello Antoine,

I get it’s a difficult task, here is the log.

No plugin or any effect added to play on the Cayin.
Adding it works flawlessly with RU6 dongle.

I really want to have Audirvana a my sole player!

A couple of things to adjust… however, you must ask why the N8ii (from the same company as RU6) is giving you problems… If the N8ii is playing fast, this is a synchronization issue at the DAC…

=================== AUDIO DEVICE ========================


Active method: Local

Max. memory for audio buffers: 13312MB

Local Audio Engine: CoreAudio
	Exclusive access: ON
	Integer mode: ON
	Use max I/O buffer size: OFF

• Lower the audio buffer pre-load RAM to 6GB… you are using more than 50% of your system RAM for pre-load buffering.

• Set ‘Use max I/O buffer size:’ ON

[Robert_F]

Thanks for the feedback!

I modified the buffer size but I can’t find this option in the menu:

@Agoldnear

Set ‘Use max I/O buffer size:’ ON

Also it looks that this is track related.
I found at least one album that can be played well.
No idea how different it is from others.

[Agoldnear]

Also make sure Audio MIDI Setup is configured for the maximum sample-rate of the DAC (768kHz).

[Robert_F]

Thanks @Agoldnear, I understand that the entry name was updated.
So I spent some time playing with every parameters but none is effective aleas.

I activated the option ‘mute while rate change’ and this time I do not ear another track
but it is silenced. Looks like a deep bug in the engine that jumped from one buffer to another.

Also Audirvana device decoding report does not correspond to the device.
N8II is 32 bits / 768 kHz, DSD 512, report display up to DSD 256. Not sure if this can help.

Else when my few working titles the rendering is really at the expected level.

[Robert_F]

I renamed the topic since it does not concern database file but seems to be specific to cayin <=> usb

@Robert_F

Also Audirvana device decoding report does not correspond to the device.
N8II is 32 bits / 768 kHz, DSD 512, report display up to DSD 256.

SIcne you are using a Mac device, you can’t get DSD 512 on your device macOS is not able to send raw DSD streams. That’s why the DSD over PCM standard has been developed: to send raw DSD in a fake PCM stream.
To identify it as such, there are 8 bit markers in it.
And the presence of these markers doubles the need of bandwidth, thus explaining why on a mac only half of the max DSD rate is available.

@Robert_F

I activated the option ‘mute while rate change’ and this time I do not ear another track
but it is silenced.

Do you only have this behavior while playing a DSD track?

[Agoldnear]

1411.2kHz is the DoP 1.1 PCM carrier sample-rate for DSD512 (22.4MHZ)… DSD512 is usually transmitted as raw 22.4MHz via i²S interfacing… However, in Windows, using the proper I/O driver, this can be transmitted via USB to a compatible DAC. Realistically, there are no recordings done as native 22.4MHz, 1-bit PDM (DSD), these are up-converted (modulated) from lower DSD sample-rates. …

The N8ii supports up-to DSD256 via DoP 1.1, and this represents typical real-world recording sample-rates of those few recordings made at 11.2MHz DSD or modulated from lower DSD sample-rates to DSD256 (11.2MHz)…

From the specs of the N8ii:

PCM speed anomalies are going to be related to a sample-rate synchronization mis-match within the N8ii, as Audirvana is the sample-rate ‘Master’… perhaps the N8ii is not configured properly as a USB DAC.

[Robert_F]

Very instructive insights, I only have a superficial understanding of containers format and transmission. Gonna, slowly dig into this.

Thanks to your question I was able to pinpoint that everything encoded in 16bits is faulty.
So your suggestion about sync may apply specifically in this case?

From the player I can change amp and dsd parameters but nothing related to freq or buffer.
Thoses are auto detected and managed.

I really love the spécial Audirvana decoding signature.
