OSS alsa fun

I typed in alsamixer -c2because one of my audio interfaces suddenly had only output on one of the two channels.

As a rule, in Linux and any other Open Source OS, you don't reboot like a moronic end user, to fix a problem:

• troubleshoot the problem
• Isolate the problem
• when hardware relation is established
• check which kernel module needs to be flused
• rmmod mod_name
• insmod mod_name
• read the man-page for the kernel_mod

I executed the above steps (stepping over the kernel mod slush) and came in the alsamixer to see that there finally is a massive update to the alsamixer for this interface

What I needed to do is pull one fader up in the mixer and get the audio balance again. As a bonus I can now balance the output of the device in alsamixer, instead of on the rack-mount instrument mixer in my effects rack.

sources:

man alsamixer
man rmmod
man insmod

This is how the Linux kernel mailing list looks like from a browser.

From a mobile browser it looks less polished.

It's a *mailing list* you should read it from a email client, not a memory hungry browser, but if you are in the links browser it will look fine. Links is light ;)

The message is important; if you keep up with kernel development on the Linux side section audio drivers, you may find it interesting

🎙️ Spent ~35 hours reverse-engineering the Apogee ONEv2 USB audio interface on Linux:
• 2 kernel patches to sound/usb/
• Vendor init sequence found via Wireshark on macOS
• Hardware watchdog keepalive daemon
• ALSA sees Playback and Capture PCMs
• Playback PCM opens — stable streaming not yet cracked

Anyone want to pick this up?

ich möchte Schallplatten per Receiver Bluetooth Audiostream auf meinen Linux-Mint-Rechner digitalisieren (Audacity).
Übertragung BT-Box: OK
BT-Verbindung Receiver to Linux: OK
-wireplumber: BT (codec SBC-XQ)
-Audio-Gateway (A2DP-Quelle und HSP/HFP AG)
es hat schon einmal funktioniert und ich habe Platten digitalisiert
hab mit aber das HowTo nicht aufgeschrieben..... :(
für eine Anleitung wäre ich sehr dankbar :)
