That is advertizing copy.

The PCIe stuff in the kernel is probably optimized for throughput to make the best use of Video cards, fast ether net, etc. Means larger chunks of data for less overhead. Maybe higher latency too. It shouldn't be as it is faster than PCI which handled things just fine. The extra throughput should actually help for higher channel counts.

I have lots of ideas :) but my knowledge is limited. The IRQ logic on the new MB chipsets is interesting (to say the least) as it has to handle a number of standards (from dos to now, five or six)... I have not read the whole thing, just about the internal audio stuff which may be useful as outputs in some situations because most of them have 8... might make good headphone mixes. But while the outputs are often 24 bit, the inputs are most often 16 and there are only two... and the preamps are less than useful. Anyway, the MB glue logic may be of some importance in all this too. All of our (linux based) audio with MB research seems to be from the PCI era. We need something new. -- Len Ovens www.OvenWerks.net _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
