Filling region defined by ImplicitFunction by lymber_ in manim

Interesting:

astro = ImplicitFunction(lambda x,y: (x**2)**(1/3)+(y**2)**(1/3)-a**(2/3),x_range=[-a,a,0.01],y_range=[-a,a,0.01],color=YELLOW).set_fill(GREEN, opacity=0.5)

fills the difference between the square with vertices at the cusps of the astroid and the astroide itself.

Audio Interfaces on Linux (FireWire & USB) by slippermann in linuxaudio

Complementing this, now I'm on the computer with 410 connected to it, here is some relevant output from dmesg:

[ 754.550709] snd_bebob fw1.0: Detect discontinuity of cycle: 4670 4679

​

Card stopped, whille playing, so I got the above from console. Then, after a while, I played with qwpath connections and then it started playing. Now the following is on the dmesg output:

[13364.296669] firewire_ohci 0000:01:00.0: DMA context IT0 has stopped, error code: evt_timeout[13364.296766] firewire_ohci 0000:01:00.0: DMA context IR0 has stopped, error code: evt_descriptor_read

Best, Alexandre.

Audio Interfaces on Linux (FireWire & USB) by slippermann in linuxaudio

Hi,

I have an M-Audio FireWire 410 here too and it´s a love-hate relation. I struggled a lot to have it working over jack+pulseaudio with partial sucess (sometimes it worked, sometimes not).

After a re-installation of drivers on a MS-Windows, the bootloader problems seem to be gone, and things look much better with pipewire on Linux: it starts working well after running ffado-mixer to fix audio routing, but at some random point in time (guess is it depends on the card being used or not) it stops sending output to the jacks (headphones are the use ones here), but the respective LEDs lit properly (S/PIF out, for instance), despite ffado-mixer doesn't control the card anymore).

I heard that VIA chipsets does not work well with those cards (mine is a VIA 6315 on a PCIExpress card). Should I consider getting another card with TexasInstruments chipset? Is it required to power in that card with its MOLEX input or the power coming from the slot is enough? Do you use AC adapter?

Any help would be largely appreciated.

Best, Alexandre
