Devuan Excalibur install LXDE, Alsa and only internal sound card.

devuan_dk_fan · Yesterday 20:24:20

I am trying a new install on a computer, using LXDE, Alsa and only internal sound card to try to get midi over web to work with a hifi setup of Alsa.

$ cat /proc/asound/cards
 0 [NVidia         ]: HDA-Intel - HDA NVidia
                      HDA NVidia at 0xfc080000 irq 80
 1 [Generic        ]: HDA-Intel - HD-Audio Generic
                      HD-Audio Generic at 0xfc540000 irq 81

I have created an ~/.asoundrc file with the following contents:

$ cat ~/.asoundrc
defaults.pcm.!card Generic
defaults.ctl.!card Generic

which at this time works with midi over web. How do I find out which of the /usr/share/alsa/ucm2/Intel/ HiFi.conf files to use?

Are you able to copy and paste half a dozen commands into the terminal in the correct order without missing any?

Hi. I have done it before...

It seems to be a real challenge for many Devuan users.

fftrate is easy to compile and easy to use.

Igor, how does installing fftrate have anything at all to do with the OP's question?

devuan_dk_fan · Yesterday 22:44:02

OK, I will check it out. However, it should be noted that I again have the problem after a restart, where all of the audio output (speaker test, youtube, etc.) functions properly (with the correct sound card), but midi over web has stopped working - again. This is before any changes in the quality of output have been made.

@ greenjeans From the related thread, it looks to me as an attempt to bypass the current Alsa patches from the install. As a point of reference, it can't be any worse than my current experiences with Alsa, and the semi functional Pipewire.

If "HiFi" means 192kHz 32-bit audio, then fftrate is a viable option. It supports high-resolution formats, including DXD (24-bit 352.8kHz), and provides high-quality real-time resampling via FFT, making it suitable for bit-perfect playback on compatible hardware like Intel HDA codecs.
