Some USB audio interface devices use an ASIO driver recommended by their manufacturer. Is there something that I can do with my PC to pass the test? Or must I invest in a new one for the sake of Jamkazam? Obviously, I don’t want to lay out a lot of cash and then discover the purchase does not solve the problem or was unnecessary for addressing it. It has 4.0 GB DDR2 memory, with Task Manager showing 2.1G, 55%, in memory utilization without Jamkazam or Reaper running. The CPU of my PC is an Intel® Core2 Duo CPU T6600 2.20GHz. I have observed that the processor utilization percentage reported by Jamkazam for my VAIO using Rearoute ASIO are considerably higher than those for the bass player using Realtek. But it leaves the question of what to do about the I/O test problem. Nonetheless, this result was encouraging since I finally obtained low latency for a setup using a superior microphone connected to the Behringer. In a response to the marhdeth posting, Nick Blair reported having the same problem, and the thread does not posit a solution. However I was not able to successfully add this gear configuration to my audio profile, failing the I/O rate and variance test. Using a 2.5 ms frame size, I brought latency down in the jamkazam test to 5-6 ms. If I retry WMW USB again, would we still have problems playing together?Īfter reading an excellent Jamkazam forum posting by marhdeth ( ), I followed the recommendation, trying the Reaper DAW. Inexplicably it seemed easier for us to play together when I used ASIO4ALL than WMD USB Audio. There was a tendency for our tempo to slow down during a tune, so I decided to go back to using Realtek for rehearsals.ĭeciding to check out ASIO4ALL for myself, I discovered that I could not successfully use the smaller frame sizes (around 2.5 ms.), needing to set my frame size to 10 ms, to get intelligible audio. ![]() Latency increased to 20ms, making it difficult to play together. While Behringer recommends using ASIO4ALL for its Q802USB, many Jamkazam users have noted problems with it, so I tried using the Windows WMD USB Audio driver first. Nonetheless, I bought the Behringer hoping to be able to use a better microphone while retaining low latency, so far without success. Jamkazam’s only “complaint” was that I was using WMD, not ASIO. My latency was low, around 5-6 ms., and my jitter was generally acceptable. I first tried the Realtek WMD after initially installing Jamkazam, before purchasing the Behringer, using my PC mic to pick up audio. I have been considering the following options, which I will discuss below. The bass player has been exclusively using Realtek WMD so far, though he too has recently acquired a Behringer audio interface and may be confronted with similar issues. My observations in this posting are based on Jamkazam sessions with the bass player, though I aspire to play with others at greater distances as well. I have been using Jamkazam predominantly to rehearse with an acoustic bass player who lives not far from me. ![]() I have an acoustic piano, an old Sony Vaio PC and a newly-purchased Behringer XENYX Q802USB. I am having difficulty figuring out the best way for me to setup my gear for playing in jamkazam sessions.
