## Case Name: check alsabat
5+
##
6+
## Preconditions:
7+
## This test case requires physical loopback between playback and capture.
8+
## playback <=====> capture
9+
## nocodec : no need to use hw loopback cable, It support DSP loopback by quirk
10+
##
11+
## Description:
12+
## Run two alsabat instances concurrently, one on each specified PCM: playback
13+
## and capture.
14+
##
15+
## Warning: as of January 2024, "man alsabat" is incomplete and
16+
## documents only the "single instance" mode where a single alsabat
17+
## process performs both playback and capture.
18+
##
19+
## Case step:
20+
## 1. Specify the pcm IDs for playback and catpure
21+
## 3. run alsabat test
22+
##
23+
## Expect result:
24+
## The return value of alsabat is 0
25+
##
