Speaker/Mic selection by Name instead of Id

[alexylem]

Change selection of Speaker/Mic during Installation / Settings to pick from Name instead of manually typing the card & decide Ids.

Thanks to @guillaumef

Using the card name is more reliable than using the id

You can get the name here:

$> cat /proc/asound/cards

I have doubts the card name will be enough.
For example in my Raspberry Pi, for speakers, card ALSA has two devices, one for Jack and one for HDMI.
So the card name does not seem to be discriminent.

[guillaumef]

You can add 'device [INT] and subdevice [INT]' after card if needed.
The card target goal with the string is still efficient with mixed sound hardware. But the subdevices will always be enumerated in the same order in a card.

Also, 'aplay' only displays the playback devices. It is not showing capture devices like dedicated usb microphone.

Another disruptive example is my desktop... for this, it is not efficient at all, i have 3 screens...

 0 [HDMI           ]: HDA-Intel - HDA Intel HDMI

  Subdevice #0: subdevice #0
card 0: HDMI [HDA Intel HDMI], device 8: HDMI 2 [HDMI 2]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

The best of both world could be to:

• add device-ID if wanted device is not the first one (my desktop case if i need the device 8)
• add subdevice-ID if wanted subdevice is not the first one (your rPI example)

[alexylem]

Yes to list capture devices I already use arecord -l
I will do as suggested, mix of both if needed.

Hi everyone,
I post here because i've got a problem with the AK5371 USB microphone.
I need it for use with jarvis, before i try with my logitech webcam and everything work perfectly, but i have to speak too near from the webcam for be heard.

I use a raspberry 3 with OSMC

osmc@osmc:~$ lsb_release -a

No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux 8.8 (jessie)
Release:        8.8
Codename:       jessie

So i buy an USB micro AK5371 this one :

So i plug it and go in the settings of jarvis but no sound detect.

So i do :

$> cat /proc/asound/cards

 GNU nano 2.2.6                  File: /proc/asound/cards

 0 [ALSA           ]: bcm2835 - bcm2835 ALSA

                      AKM AK5371 at usb-3f980000.usb-1.5, full speed

and :

$> aplay -l

In .asoundrc, i was with hw1,0 (same than my webcam)

capture.pcm {
     type plug
     slave.pcm { type hw card AK5371 }

So i tried again jarvis and nothing change.
So i check alsa mixer, choose the card and microphone, no problem, but when i try to record a wav for testing, nothing record ... i try to found some solutions but nothing work and i see you got the same microphone so i ask some help, because i can't believe is work on windows a

PS : the microphone work directly when i plug it in my computer (windows) and not on linux ;)
Thanks for your help and sorry for my english, i'm french ^^

If you need other information, just tell me ;)

PS2: I found the Alsa script for information of my raspberry :
