Find Sound card details in Linux/Unix

Sound card is a hardware device which will give a machine the capability to play audio files and audio in video file for us. In this post we will see how to get sound card hardware and sound card driver details. We already covered following stuff in this «Know your hardware in Linux» series.

Example 1 : F ind number of sound cards present in your machine

0 [PCH ]: HDA-Intel - HDA Intel PCH 
HDA Intel PCH at 0xc2600000 irq 45

If you see there is only one sound card which is HDA-Intel sound card which is an inbuilt one.

/proc/asound/cardX

Where X indicate no of cards, if you see card0, card1 then indicates you have two sound cards.

to see number of cards available

 
dr-xr-xr-x 5 root root 0 Jun 9 12:08 /proc/asound/card0

Example 2 : How to get card manufacture details using lspci command.

00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04)

Example 3: How can I check how many number of devices attached to sound card like speakers, mic, woofers etc

cat /proc/asound/devices

1: : sequencer 
2: [ 0- 3]: digital audio playback 
3: [ 0- 0]: digital audio playback 
4: [ 0- 0]: digital audio capture 
5: [ 0- 3]: hardware dependent 
6: [ 0- 0]: hardware dependent 
7: [ 0] : control 
33: : timer

From the above output we can see that there are two audio playback devices(Speakers) and an audio capture device(A mic) to this machine. And remaining details are sound card related information. Or we can use aplay command as well to get device details

aplay --list-devices

 
**** List of PLAYBACK Hardware Devices **** 
card 0: PCH [HDA Intel PCH], device 0: ALC270 Analog [ALC270 Analog] 
Subdevices: 1/1 
Subdevice #0: subdevice #0 
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0] 
Subdevices: 1/1 
Subdevice #0: subdevice #0

Example 4 : How can I get which Kernel module or sound driver details for my sound card. The module related to sound card is represented snd string in it’s name. So if we can search /proc/asound/modules file or lsmod command output we can easily find which sound card driver is in use as shown below

grep snd /proc/asound/modules

0 snd_hda_intel

lsmod | grep snd

 
snd_hda_codec_hdmi 32049 1 
snd_hda_codec_realtek 78147 1 
snd_hda_intel 33492 3 
snd_hda_codec 134213 3 snd_hda_codec_realtek,snd_hda_codec_hdmi,snd_hda_intel 
snd_hwdep 17699 1 snd_hda_codec 
snd_pcm 96668 3 snd_hda_codec_hdmi,snd_hda_codec,snd_hda_intel 
snd_seq_midi 13325 0 
snd_rawmidi 30513 1 snd_seq_midi 
snd_seq_midi_event 14900 1 snd_seq_midi 
snd_seq 61555 2 snd_seq_midi_event,snd_seq_midi 
snd_timer 29426 2 snd_pcm,snd_seq 
snd_seq_device 14498 3 snd_seq,snd_rawmidi,snd_seq_midi 
snd 78921 16 snd_hda_codec_realtek,snd_hwdep,snd_timer,snd_hda_codec_hdmi,snd_pcm,snd_seq,snd_rawmidi,snd_hda_codec,snd_hda_intel,snd_seq_device 
soundcore 15048 1 snd 
snd_page_alloc 18485 2 snd_pcm,snd_hda_intel

Example 5: How can I find sound card software version in Linux?

cat /proc/asound/version

Output: 
Advanced Linux Sound Architecture Driver Version 1.0.25.

A good documentation about /proc/asound folder can be found at http://alsa.opensrc.org/Proc_asound_documentation

In our next post we will see how to find details about network card like network card manufacture, MAC address, drivers etc. Stay tuned.

Порядок определения звуковой карты

В некоторых устройствах первой звуковой картой определяется HDMI-порт, либо другое нежелательное устройство, которое не может воспроизводить звук. Для исправления порядка загрузки звуковых карт сначала требуется узнать под каким порядковым номером распознается необходимая звуковая карта. Для этого выполните команду:

Она покажет примерно такой вывод:

**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: CONEXANT Analog [CONEXANT Analog]
