#271: XRUNs on FA-66: Instantanous samplerate more than 1% off nominal -----------------------------+---------------------------------------------- Reporter: joh | Owner: Type: bug | Status: new Priority: major | Milestone: Component: devices/bebob | Version: FFADO 2.0-rc2 (1.999.42) Resolution: | Keywords: Device_name: | -----------------------------+---------------------------------------------- Comment (by arnonym): Replying to [comment:10 joh]: > Replying to [comment:9 nils]: > > I strongly concur with [comment:7 cladisch] that people experiencing this should try out their latest open source drivers -- IMO tweaking firewire parameters will hardly make proprietary video drivers behave. I think it boils down to whether you rather want higher video or audio/firewire performance. > > Having to make a choice between video and audio is unacceptable. The open source drivers are not an alternative either, as they lack many features such as 3D acceleration. Its not a choice between audio and video, its a choice between things we can control and things we can't. Open source drivers are something we can control. We can see the code and see what they do in kernel- and userspace. Closed source drivers (regardless whether its video or something else) in kernel-space have complete access to all kernel things and can do whatever they like. And we don't know what they actually do because we don't know the code. They say its a video driver but we don't know what parts also effect other parts of the kernel, they could do all nasty things slowing down all other devices (like firewire-io) in order to ''optimize'' your video. This makes it basically impossible to debug anything. And because of this uncertainties, most (all?) kernel- and driver- developers refuse to debug anything if a proprietary driver is loaded. (Apart from any philosophical issues.) > Is this another argument for having ffado in kernel space? No, its an argument for open-source-drivers. We are not asking you to completely drop your nvidia driver forever, we just ask you to check whether the same problems happen with the free drivers and then help debugging it. And if it only happens with the closed-source drivers, well... -- Ticket URL: <http://subversion.ffado.org/ticket/271#comment:11> FFADO <http://subversion.ffado.org/index.fcgi> Free Firewire Audio Drivers |
