$ lspci | grep -i audio 03:00.0 Multimedia audio controller: Creative Labs SB Audigy (rev 03)Ġ3:01.0 Multimedia audio controller: VIA Technologies Inc. The SOUND_CARD_PCI_ID can be obtained like so: # setpci -v -s $SOUND_CARD_PCI_ID latency_timer= ff You may also want to maximize the PCI latency timer of the PCI sound card and raise the latency timer of all other PCI peripherals (default is 64). etc/sysctl.d/90-max_user_nf fs.inotify.max_user_watches = 600000 This again can be done on the fly with sysctl fs.inotify.max_user_watches=600000 or in a dedicated configuration file: 600000, that inotify keeps track of for your user, can help with applications, that require many file handles (such as DAWs).

Increasing the maximum watches on files (defaults to 524288) to e.g.

This can be done on the fly with sysctl vm.swappiness=10 (see sysctl(8)) or setup permanently, using a configuration file (see sysctl.d(5)) such as: 10 will make the system wait much longer before trying to swap to disk (see wikipedia:Paging#Swappiness).

Reducing swappiness (aka swap frequency, set to 60 by default) to e.g.

# echo 2048 > /proc/sys/dev/hpet/max-user-freq # echo 2048 > /sys/class/rtc/rtc0/max_user_freq

Increasing the highest requested RTC interrupt frequency (default is 64 Hz) by running the following at boot:.

Add noatime to fstab (see Improving performance#Mount options).

Using the threadirqs kernel parameter (consult for reference) - enforced by default by the realtime kernel patchset.by installing realtime-privileges and adding your user to the realtime group). Setting the CPU frequency scaling governor to performance.You may want to consider the following often seen system optimizations: Only if you require a setup with lower latency and greater stability, start considering optimizations! Try a standard setup with the vanilla Arch Linux kernel first. While for some systems and setups a higher level of optimization is necessary, for most users this will not be the case. Note: The quality of information on best practices and system configuration vary a great deal (and are outdated or sometimes even contradictory in many locations).

Therefore, you will need to install and setup one of the available sound servers which are outlined soon.

To finish with optimizations, these ultra low latency operations may require you to set up a #Realtime kernel.Īlthough some pro audio software can work with ALSA directly, most of the #Applications mentioned later are JACK Audio Connection Kit or JACK clients. Applying further #System configuration will be necessary only if you are experiencing audio drop-outs (also known as glitches) or if you need (or want) to reach ultra-low latency operations. Have I set up sound properly? $ speaker-testĪ vanilla Arch Linux kernel is sufficient for low latency operation in most use cases. a USB audio interface and keep in mind integrated soundcards), you would want to set the default sound card. If you are using multiple audio devices (e.g. However, "no sound" is likely a simple unmuting the channels problem in ALSA's mixer configuration. If this is not the case, you must solve the problem before going any further. ALSA should work out of the box with a default Arch installation.

Getting startedĪfter reading the Sound system article, you might be aware that Advanced Linux Sound Architecture or ALSA is part of the Linux kernel and used for drivers and interface on Arch Linux as the default Sound system.
