I had the same problem and I followed Ubuntu's troubleshooting guide completely but it didn't work. It finally worked by adding the below line to /etc/modprobe.d/alsa-base.conf options snd-hda-intel model=auto

I also deal with this still. I'm a long time Linux user, about to throw in the towel. I can't stand all these silly bugs because some developer is too lazy to fix it, and expect the average user to know programming enough to do it themselves. I'm no programmer, but have been using this OS long enough to see a slow decline (only an incline in Android).

The most complete recording, editing, and audio mixer software is Ardour. This software is based on Jack rather than PulseAudio sound server. Ardour can be installed from the Software Center but it will likely better be integrated in the Ubuntu Studio flavour of Ubuntu. If it is only a single or few LADSPA plugins we can also integrate them to the ...

I have the same problem on my pc: It appears that effectively alsa restores SPDIF "unmuted" state during boot, but then pulseaudio mutes it when user session starts. To verify that alsa restore is ok, just run sudo alsactl restore in a terminal and look if it unmute SPDIF. To verify that pulseaudio is the problem , just run pulseaudio -k to relaunch ...

Your main soundcard is the 2nd one (the first is HDMI soundcard, attached to HDMI screen plug) . So , in Alsamixer, press F6 , select 2nd soundcard : you will see more faders .Then set volumes and unmute faders (using arrow keys and "m" key to unmute. ) You can also install and run pavucontrol (Pulseaudio volume control) to access the 2nd sound card in the ...

A way to solve this problem is to disable pulseaudio . (note that pulseaudio is usually not needed to get sound, as almost all Linux software can use alsa if pulseaudio is not active. Exception is Skype which needs pulseaudio . The main problem is that you must install and use gnome-alsamixer to set volume instead standard volume applet. Another ...

-The problem with HDMI may be solved with pavucontrol (install it if needed), and choosing default device in "output tab" (clicking green button) -The problem with subwoofer may be solved by changing model as you suggest: your hda codec is Realtek ALC668 , and from this page , searching ALC66x/67x/892, you can try ASUS as model.

As suggested by @Masu WINENOPULSE=1 parameters fix the issue. There should be a way to make this setting as default in wine but I cannot find it right now. For the moment I'm using a manual approach: env WINENOPULSE=1 wine YOUR_PROGRAM.exe Or you can add it to the launcher: Taking care that Wine launchers are stored in: ...

The jack and ALSA header files should be provided by packages libjack-dev and libasound2-dev respectively.

I figured it out. It looks like it's a bug with Ubuntu probably. I went to system settngs>sound>Input tab> select microphone built in audio, and then over on the right hand side where there is the input volume and the mute button. Checkbox the mute button, and then un-check it again and that causes the microphone to start working. I hope it works for anyone ...

As CL suggested, I asked on jack-devel mailing ( http://jack-audio.10948.n7.nabble.com/Jack-Devel-USB-MIDI-keyboard-Akai-LPK-jackd-td18276.html ). The problem is that the zynjack is outdated. Morever, for connecting aconnectgui is not necessary. Let me cite Jeremy from the mailing list: This is what I would do to get things going: Connect your LPK25 ...

The problem is that the default soundcard is HDMI device, not main soundcard . A way to change sound devices order at a low level (alsa) is to add this 2 lines at the end of /etc/modprobe.d/alsa-base.conf : options snd-hda-intel index=0 model=auto vid=8086 pid=9c20 options snd-hda-intel index=1 model=auto vid=8086 pid=0a0c then reboot. (the "vid" and ...
