Q: El Capitan USB audio problems.

I just installed EL Capitan on my Late 2012 Mac mini. I have connected NuForce Udac2 DAC to usb port and it constantly disconnects from computer. I can't play any audio thru DAC. Tried changing midi settings, reseting Pram nothing changes. On windows PC dac is working without any problem. Everything worked OK in Yosemite.

 

There is obviously some problem with USB audio in EL Capitan.

DO NOT UPGRADE to EL Capitan if you have some USB audio cards important for work.

 

This problem came up in beta releases and still Apple did not fix it. This is a HUGE let down for me, especially considering how many people use Dacs or usb speakers these days. 

 

I guess there is no difference between Apple and Microsoft these days. Everything that is released is not a finished product.

 

Guess I'll have to wait for 10.11.X for a fix...

Again, awful job Apple.

    FWIW: If you had a full backup of your partition, preferably a clone, you would have little risk in trying Sierra out for yourself.

     

    No one here is going to have your exact mix of software. You need to try it for yourself.

    Yes, I have just upgraded and tested, the issue is resolved:

     

    MacBook Air (Mid 2011)

    macOS Sierra 10.12

    Hi,

     

    I am also using KEF X300A for desktop speakers. Previously the pair was used with foobar2000 on Windows 7 and they worked perfectly together. When I changed to Macbook Air with El Capitan, the music player has been VOX. It sounds, as I perceived, not as good as foobar2000 did, but the quality still acceptable. There has been no disconnection issue as many people described. My Mac OS is 10.11.6.

     

    The problem for me now is with video players. I tried Media Player, Mac Media Player, VLC. When the volume was increased, it created distortion. The sound effects of movie have not been impressive as they have in Windows.

     

    Has anyone upgraded to Sierra? I read an article online that it would solve the usb audio issues.

    Well, my issues with the KEFs were not fixed with Sierra. In fact, a new issue was introduced. Now on every startup or restart, I have to readjust the left to right channel balance.

     

    And, disconnects occur more frequently, but srtill at random. Using the DVD Player app seems to produce more dropouts.

    Definitely not fixed with an AudioQuest Dragonfly Red in Sierra.

     

    Certainly minimized, but I've already had several occasions where I needed to remove and reconnect the stick to clear things up.

    I've been thinking about rolling the dice and purchasing a Schiit Wyrd: http://schiit.com/products/wyrd But, haven't found any testimonials for its use with KEF X300As.

     

    Probably not a good financial option for use with a AudioQuest Dragonfly.

    My Nuforce Icon DAC is not recognized in Sierra.
