Re: MX-17.1/MX-18.1: Replacing PulseAudio by ALSA's sound server – implications?

Just a general request, your posts are a LOT more pleasant to read when you leave all the boldings out. 
Let get one thing straight pulseaudio has nothing to with the actual sound driver itself that is the job of (alsa) no alsa > Pulseaudio is useless it producers no sound at all. It is a mixer and a channeller for your devices speakers , mic etc.
Can pulse effort your sound yes it can mostly because alsa has it own mixer equalizer preamp settings.
If you use asound.conf found in etc/asound.conf you are setting up system wide sound. If you choose to use .asoundrc.conf found in home/asoundrc.conf you are setting up sound on a per user level this file is added by the user. (I prefer asound.conf)
All you need to do is remove pulseaudio and pavu.. Some users have to install apulse meaning (alsapulse) to let alsa sound work in their browsers as for some strange reason they will only produce sound with pulseaudio. I myself do not use apulse as I run Waterfox and qutebrowser. Music mpd and ncmpcpp
The first thing you need to do after removing pulse and company is find out what sound card you have and its id number this is done using your terminal with this command = cat /proc/asound/cards
This is my readout and I want to use my USB Audio so the device id number is (2)
Code: Select all
15 files = 1003M ~ >$cat /proc/asound/cards
0 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xf7130000 irq 29
1 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xf7080000 irq 17
2 [US2x2 ]: USB-Audio - US-2x2
TEAC Corporation US-2x2 at usb-0000:00:14.0-10, high speedNow all I need to do is edit my asound.conf file and make device 2 the default sound device as below. (using sudo with your editor)
defaults.pcm.card 2
defaults.ctl.card 2
Set default sound card... Must be done from sudo
After this Open alsa mixer with sudo press F6 or S select your card then type sudo alsactl store. Also the below is not needed with antiX as sudo antiX-cli-cc = control centre is run as root anyway and works.
sudo alsamixer
sudo alsactl store
That is it you should now have your sound card running with alsa.
If you want a bit more info on asound.conf equalizer , pre amps this is the asound.conf from antiX and you can adjust the settings in the file. Note this line (Requires alsa-utils libasound2-plugin-equal)
