Microphone issue with Lenovo Ideapad 330 under Ubuntu 22.04 #2204 #lenovo #alsa #microphone #ideapad

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

Fedi, I'm at a total loss on how to sort this one out. I've got an Elgato wave: 3 that worked great for 18 months and one day after updates it stopped registering input.

Its odd, it shows up normally in ALSA and pipewire. Volume and mute status work in software and hardware and accurately update when one is changed.

It just won't let me talk into it 😥.

У меня нет звука, но я должен слышать: история одной регрессии ядра

Что делать, если после очередного обновления Linux на старом ноутбуке намертво отвалился звук, а в логах висит зловещее CORB reset timeout и 0xFFFF ? Переустановка аудио-серверов не поможет, параметры загрузчика GRUB система упорно игнорирует, а LTS-ядро больше не гарантирует стабильности. В этой статье разбираем, как спуститься в логи dmesg , понять, почему устройство «задыхается» на шине PCI, и заставить ядро заново проинициализировать аудиокарту «на горячую» с помощью sysfs и systemd.

I always use alsamixer -c0 up to cxx from the OSS ALSA period since it's ncurses based & faster than GUI programs.

Many things in Linux were changed for good reason, but some are questionable. I don't use systemD init is easier to maintain. It aint broke so KISS

Pipewire is fun to add FX in my signal chain to my DAW, but for serious work I have a physical FX rack.
I love pavucontrol

Hello I need some help about connecting a #RolandFP-90X -> bluetooth midi -> Ubuntu.

aconnect shows

0 'FP-90X MIDI Bluetooth'

aseqdump -p 128:0 do not shows any midi event arriving to the computer..

It seems that the keyboard is transmitting throught chanel 1..

I'm stuck here, still searching :)

- The monolithic way. By using one application, like a DAW, you only have to fire up one application that sets up your music making environment for you. The advantage is that you don't have to start any other application like #JACK and/or a session manager, especially when you use plain #ALSA as the audio backend. The disadvantage then of course is that any other application won't be able to play or record audio anymore.

@jwcph

ALSA are drivers to talk to hardware - 90% of audio interfaces (whatever enables you to plug an audio cable into your computer) use ALSA. (exceptions are FireWire interfaces and some other). if a new audio interface is 'incompatible' with Linux, it means it doesn't have an ALSA driver (aka kernel module) - yet.

on top of #ALSA drivers (so, using those drivers) there were two systems in last decade:

1. PulseAudio - designed to be invisible way to handle all desktop audio - mutiple application would be able to send sound to your audio output (to ALSA). not capable of low-latency audio needed for professional music/audio work. if you had multiple outputs (ALSA), like HDMI or analog out, you could choose one of those for a particular application (like web browser), and similarly for inputs (microphones etc)

2. JACK audio server - low latency, designed for pro audio work, allowed completely free patching between multiple applications (ins and outs), standalone audio plugins, and audio interface(s) - essentially infinite patchbay among "everything". all decent audio apps work with JACK, but not 'desktop' apps, something like web browsers for example.

at first #JACK and #PulseAudio were incompatible - you were supposed to suspend (or uninstall) PulseAudio in order to use JACK and vice-versa. they fought for access to ALSA. Later on, bridges were developed so you could send sound from web browser (that was using PulseAudio) to your DAW (that was using JACK) or output from DAW to OBS or Zoom...

audio apps needed code to talk to any of these two systems. they needed to be compatible with JACK, or/and PulseAudio.

last few years PipeWire ( @pipewire ) appeared to replace JACK and Pulse at the same time and be very transparent and invisible but still configurable if you so needed. Like JACK and PulseAudio it also sits on top of ALSA drivers, but "acts" like it's Pulse and/or JACK. the idea seems to be that replacing JACK and PulseAudio is easy if nothing needs to be changed in those apps. so applications think they are sending audio to JACK but are actually sending it to PipeWire 'in disguise'. it's extremely good at pretending (tech speak: it uses same API). So, if you are using (running) PipeWire, you cannot use (run) JACK or/and PulseAudio.

PipeWire is amazing solution. it also automatically discoveres new audio devices like usb headphones, or Bluetooth speakers and makes the default audio output. you can unplug your audio devices and apps won't notice. It's still a bit rough on the edges, but it's getting better and better.

MIDI? well, it's complicated: there's ALSA MIDI and JACK MIDI. Just two different systems trying to do patching between apps. So some apps will show one, and some the other. I think PipeWire tries to make this irrelevant by bridging these two, but it's not always successful. It should be accessible in PipeWire patchbay app like 'qpwgraph'.

Sorry if that's too long, but I hope it is understandable enough. And sorry for so many edits.
