Arecord not working #6

Open mintu19 opened 5 years ago

mintu19 commented 5 years ago

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

karostami commented 5 years ago

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

xiongyihui commented 5 years ago

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

mintu19 commented 5 years ago

Yes i had installed Fifo plugin.

karostami commented 5 years ago

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.

xiongyihui commented 5 years ago

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

xiongyihui commented 5 years ago

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

karostami commented 5 years ago

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

mintu19 commented 5 years ago

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...
