Arecord not working

[mintu19]

When i try to record mic using arecord with ec, i get error

ALSA lib pcm.c:7448:(snd_pcm_slave_conf) Unknown field type
arecord: main:788: audio open error: Invalid argument

How to solve this

I have a similar mistake.
Did you correct this error?

Can you provide more details? Did you install the FIFO plugin?

[mintu19]

Yes i had installed Fifo plugin.

[karostami]

Yes. I install too, i use in Raspberry zero pi. when I use the pulse audio is everything O.K. But without it, i get error.

It seems that the FIFO plugin is broken. Trying to figure it out~

[xiongyihui]

The asound.conf had an issue. just fixed it.

[karostami]

Thanks. It is O.K!
But when I use arecord then stop it, ec is suddenly stoped!

[mintu19]

Same issue... Ec stops with ctrl+c on arecord...

Also recorded voice is flat like a playing at 1/2 speed... I will file another issue for that after testing more and if issue persists...
