Hi,<br>
<br>
Just looking at updating from 9.10 to 10.04 and was wondering...<br>
<br>
- has 10.04 got an rt kernel?<br></blockquote><div><br></div></div><div>NO for the i386 and a preemptive for the 64bit version, also available RT kernels at abogani PPA</div></div></blockquote><div><br>A -rt kernel is available in the official Ubuntu repositories, however, it is based on the 2.6.31 kernel. This should be contrasted with the -generic kernel that is also available but is based on 2.6.32.<br>
<br>So, you could choose to use the 2.6.31 -rt kernel but you would chance loosing the improvements that the 2.6.32 affords.<br><br>Lastly, I would point out that I have been recording with the 2.6.32 -generic kernel and have been having a smashing good time with it. With an M-Audio Delta 44 (and even the Soundblaster Live) card I have been recording with a latency of 11 msecs and not having any xruns (except when starting another application of course).<br>
<br>If, however, you find that the -generic kernel is not enough for you, Alessio Bogani (the Ubuntu Studio Team kernel guru) has suggested trying the -preempt kernel next, especially on laptops because this kernel flavor doesn't sacrifice power saving features (important for battery life). This kernel may not be available for 32 bit machines as Ricardo mentions.<br>
<br>If the -preempt kernel isn't enough, then Alessio suggests using the -lowlatency kernel next.<br><br>And lastly, if nothing else scratches your low latency itch, then you can try the -rt kernel.<br><br>I hope you find this information helpful.<br>
