Where is the ALSA base conf file for Raspberry Pi?
I have a USB sound card for my pi b+ which I want to setup as my default sound device and all the tutorials for setting up involve editing the alsa-base.conf file in /etc/modeprobe.d, but I don’t seem to have that file! Anyone able to help? I can see the usb fine when i run lsusb, and alsamixer detects it and plays audio fine.
How to change ALSA volume on Raspberry Pi?
By renaming it to start with a lowercase “k” the file is ignored and the ALSA state is not saved. As well as using amixer on the command line to change the volumes and so on, you can also use a slightly graphical utility called alsamixer. Just type alsamixer and you’ll get something like the screenshot shown below:
How does alsamixer work on a Raspberry Pi?
alsamixer on a Raspberry Pi In this utility you can move the volume up and down using the up and down cursor keys, mute and unmute using the “m” key and move from one device to another (if you have them) using the left and right cursor keys. Press the Esc key to exit.
When to disable ALSA utils on Raspberry Pi?
If you want to stop the current state being saved when the machine shuts down then you need to disable the alsa-utils init script from running when the machine enters runlevel 0 (halt) and 6 (reboot). A slightly hacky way of doing this is to execute these commands: Note that the files have been renamed to have a lowercase “k” at the start.
Where is ALSA base.conf located in Debian 10?
alsa-base.conf is no longer available in Debian 10. That doesn’t mean you can’t set your HDA options; those can go in any file with a name ending in.conf in /etc/modprobe.d, ideally a file of your own. I use /etc/modprobe.d/local.conf to store all my module options.
In /usr/share/alsa/alsa.conf I un-commented “load card-specific configuration files (on request)” and I also replaced the content of .asoundrc which is a hidden file in your home folder with: The downside of this solution is the desktop sound applet won’t appear.
How to change default sound card in ALSA?
It’s not called alsa-base.conf, just alsa.conf. All the relevant text is in that file. Just run sudo nano /usr/share/alsa/alsa.conf, change the default sound card to 1 or whatever you prefer (obviously, 0 is default so not that one).
Which is the ALSA configuration file in Linux?
You can either modify a user’s .asoundrc file to tell ALSA that user’s preferences for cards, or alter how ALSA loads modules and drivers. /etc/modprobe.d/alsa.conf (or /etc/modprobe.d/alsa-base.conf or similar) is the main ALSA configuration file in most linux systems.
How to see which card ALSA is using?
See Troubleshooting to play a file and see which card ALSA uses. At a low-level, the files cards, modules, and devices in the directory /proc/asound show how ALSA has configured itself. You can either modify a user’s .asoundrc file to tell ALSA that user’s preferences for cards, or alter how ALSA loads modules and drivers.
How to keep ALSA drivers out of default slot?
You can tell /etc/modprobe.d/alsa.conf (or alsa-base.conf, or similar) to keep a driver in out of the default slot. For example, if you have a a Creative Labs soundcard driven by the “emu10k1” driver and you don’t want it to be your default card 0, append Note the comma in this line that moves the driver to the second slot.
