I have not been able to achieve as low latencies with -generic as with -lowlatency, except for once, which was on 2.6.38-1. At the time, -generic seemed to behave exactly the same as -lowlatency, however after a system update, the same -generic kernel would not give me low latencies without audio dropouts anymore. Two of us got the same initial result with 2.6.38-1, so I'm pretty sure it was not something I dreamt :P. After that, for a good while, -generic was not usable with jackd for latencies that are required for playing soft instruments, or monitoring realtime audio processing. Now, with 2.6.38-7, -generic seems to behave a good deal better, but I can still not get the same low latency as I can with -lowlatency. Also, during this whole period, -lowlatency has been more or less, perfectly stable, and virtually as reliable as a realtime patched kernel. The diff in my tests may be more related to me picking up problems during later tests, that I didn't pick up during my first tests. Or something in Ubuntu other than the kernel is affecting that in later tests. So, my opinion is, I have still to see proof of -generic behaving as reliably as -lowlatency. -- ailo -- Ubuntu-Studio-devel mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-devel
