[linux-audio-dev] open-source like hardware

2002-01-12 Thread Pieter
Hi, I'mlurking this list for some time now, and I've now seen several threads about bad hardware support (drivers). It got me thinking about creating a (pro-) soundcard, specifically for the linux community. Not an easy job, it should be possible, although I'm not sure if I can do it (as

Erik, Have designed professional digital audio hardware in a previous job, I can tell you that is is far from straight forward, especially when you talk about more than 2 channels and try to achieve 110+ dB SNR. This is not something to be embarked upon unless you have a lot of time money and

I can help, at least with the analog part. But I don't have a lot of extra money at the moment. It will have to be low budget for me too... I'm a student, so funds are very limited. (understatement of the year candidate) I do have plenty of time and naive enthusiasm... Pieter

Hi, I've done some changes to lowlatency patched kernel. Mainly fixes to DRM drivers and few network drivers. Most probably I have done something really stupid, but those work here(tm). Especially the Radeon driver patch has got a lot of testing and seems to have huge impact to latencies in my

(cut) Maybe a better approach would be, if you are thinking about low level stuff, to use FPGA or so, but again, it's expensive. (cut) Small note: The RME Hammerfall DSP cards are built upon a Xilinx FPGA. But I don't think they have their implementation openly available :) They use Xilinx

Hi, Here's my second try. I read through the code once more and made some fixes. Is this correct way to avoid conditional_schedule() when holding spinlock? Both eepro100 and 3c90x drivers call the command completion wait routine with spinlock held in few places. I didn't find such situations in
