Re: E-mu 0404 and getting nowhere...

Are you sure the Fw will be loaded automatically w/ that package installed? I don't know the exact details, but yes, it should work. @Red Leader OK, so Linux audio is complicated, but it isn't this complicated. :) I was looking through the whole thread and you've had three problems (1) Your Echo Au...

Re: E-mu 0404 and getting nowhere...

@ Linuxmusician01 As far as I can tell you're mistaken. alsa-firmware is a package, and like any other package it could be installed from a repo or built from source. AV Linux comes with alsa-firmware pre-installed. @ Red Leader The fact that lspci showed the Emu card means it isn't completely fried...

Re: ALSA input error; JACK "You have no standard location set

I saw in your other post that you're using a Raspbarry Pi. Does it have an audio interface? I used one a while ago and the audio interface was a separate board or 'hat' I think it was called. What does

Code: Select all

aplay -l

Re: rate my xruns: tuning assistance?

@ZestieBumwhig Glad you got it working. You could post your improved results. Looking at the number of circles you got in your first results I'd estimate you have a 4GHz processor and you should now get around 12000 circles. @AlexTheBassist Do you have a USB interface? If so have you tried a non-pow...

Re: rate my xruns: tuning assistance?

I would think that you're getting Xruns at a low DSP load because your interface prefers a buffer size that is a multiple of (samplerate/1000).

Try a buffer of 96.

Other values that work are : 48, 96, 144, 192 ...

Thanks for clarifying that. 4.19.31-rt18 works on my system. I'll stick with that.

Re: anybody having problems with latest linux-rt and KDE?

@funkmuscle Are you using 5.0.5 RT? On the 3rd of March the maintainer of the AUR package posted this: I've just removed the patch for nvidia that has been used for years. Apparently it's no longer needed, have tested on 2 systems one with the current nvidia driver, and another with nvidia-340xx. Th...

Re: anybody having problems with latest linux-rt and KDE?

@Musicteacher I've got AMD drivers and Capoeira has Nvidia. It could be both graphics drivers.

It could be kernel 5.0+ is causing your thermal problems as someone posted on the Arch forum : https://bbs.archlinux.org/viewtopic.php?id=245542

Have you tried the stock kernel?

Re: anybody having problems with latest linux-rt and KDE?

I've had a problem with this kernel. My USB devices disconnect. The rest of the system carries on fine. This has happened in 5.0.3 rt and 5.0.5 rt

I'm using openbox and an AMD card with amdgpu.

Re: Worse performance when power supply plugged in!

My friend uses a laptop as his main audio system. Because he always has the power supply plugged in he took the battery out. He read somewhere that this is better for the battery. If excess heat is the problem then taking the battery out would eliminate the heat from charging the battery. If you're ...

It's not a theory. It's a fact of audio engineering.

Re: Lowpass filters cutting off 20khz-48khz?

48 kHz isn't new. DAT worked on 48kHz. 48kHz was the professional standard and 44.1kHz was the consumer standard. It's more to do with the sampling side, the A to D. If you sample a frequency higher than the Nyquist frequency you get aliasing. So everything above the Nyquist frequency has to be filt...

Re: Lowpass filters cutting off 20khz-48khz?

The minimum number of samples per cycle required to reconstruct a sine wave is two.

So the maximum frequency that can be reproduced is half the sampling rate.
