Just a note about the kernel. Different kernel versions may perform differently, so that is always a possibility. Different versions of -lowlatency may perform differently, that is.
Different hardware may give you different performance, the motherboard, and the CPU makes a difference. USB, vs PCI, vs Firewire also makes a difference. The running services and applications on your desktop system can also affect performance. One common issue has been wifi, where wifi drivers can mess things up for you. A kernel with a realtime patch may outperform linux-lowlatency, but then again it may not. Depends on how well you have -lowlatency working (some can get really low latencies). So, there are a lot of variables, but in my experience, the most important is usually the kernel, and linux-lowlatency has worked well for me. There are really only two kernel choices for audio. linux-lowlatency or a realtime patched kernel, usually called linux-rt (not available in Ubuntu repos). With linux-lowlatency you have the great upside of getting regular security updates and full compability with everything on Ubuntu. It is identical with the generic kernel that Canonical maintains, only linux-lowlatency has better performance for low latency operation. With linux-rt you generally need to know how to build it yourself, or use a third party archive. -- ubuntu-studio-devel mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-devel
