Arcam Airdac sampling rate problem

tgh · November 2, 2020, 5:44pm

I am currently trialling Audirvana and ma having difficulty connecting to my HiFi through the Airdac at any sampling rate higher than 48KHz. Although the Airdac should accept tracks sampled at 96KHz it automatically recognises only up to 48KHz. If I change the sampling rate manually to 96KHz the play button “greys out” and nothing plays. I would be most grateful for any help.

Can you paste the debug info here?

Hello @tgh,

Your DAC can go up to 48Khz when it is used in UPnP, can you check if you have a firmware update that may unlock it’s possibilities?

tgh · November 3, 2020, 12:21pm

I almost grateful for your help. I sent you a debug report from the machine working at 48KHz. Below is the report when I set it to 96KHz manually. The manufacturer’s publicity and all the reviews say that the DAC is capable of streaming at 96KHz and the firmware is up to date so I do not understand why I am having these problems. I am however very grateful for your help. Here is the debug report at 96KHz:Audirvana Mac Version 3.5.41 (3571)

Looks good, it plays at 96KHz.

tgh · November 3, 2020, 1:06pm

The trouble is that it does not. Audirvana loads a track but the pause button remains greyed out and I cannot play anything. I have tried changing the upsampling levels with no effect at all. I am baffled but wondering how much difference the sampling rate actually makes to sound. I also have an Arcam Solo Uno streamer which does work at 96KHz and have to say I am struggling a little to find much if any difference in sound quality between them - perhaps the higher notes are little clearer but it is marginal. 24 bit on the other hand does make an audible difference for me compared with 16. Once again thanks for your help I think I will see whether Arcam can help. By the way do you know if it is possible to store the profiles for two different DACs is as to be able to switch between them easily without having to change things each time? Once again many thanks for your help.

Antoine · November 3, 2020, 1:58pm

Have you checked if you have the latest version of your firmware?

tgh · November 3, 2020, 5:20pm

Thanks for the query. Yes I have. I have just done a check and have the latest update. It works perfectly at 48KHz but not at 96 - the file loads but the pause button is greyed out and nothing will play. Can you help on my other query: whether it is possible to store the profiles for two different DACs so as to be able to switch between them easily without having to change things each time? Many thanks for any help you can give me.

Antoine · November 4, 2020, 8:27am

This is a feature that is not available but we are taking a look at it as it was requested by many users.

tgh · November 4, 2020, 9:34am

Thanks for your reply. I can understand that many users have made the same request and would strongly encourage provision of that feature - it appears to me to be the one major drawback of your software at the moment. As for my specific problem I take it you cannot help further? I will contact Arcam and see what they say.

tgh · November 9, 2020, 11:56am

Arcam’s engineers have confirmed that the airDAC should play 24 bit 96KHz FLAC files so I do not understand why I cannot do so though Audirvana. Can you give any more help on this as I would prefer to use Audirvana, despite its difficulty with using 2 different output types, rather than pay for Roon which is very expensive though easier to use,

Antoine · November 9, 2020, 12:40pm

Do you have a Android device? If it’s the case, have you tried to use Bubble UPnP with it?

tgh · November 9, 2020, 3:29pm

No I’m afraid I only have Apple devices - iPhone, iPad and iMac.
