Missing error messages #249
Description
Hello 👋,
I am currently having some difficulties to use the tinyalsa api and it's utilities (tinycap) to record audio.
I have the following device:
biscuit_puffin:/ # tinypcminfo -D 0 -d 24
Info for card 0, device 24:
PCM out:
cannot open device '/dev/snd/pcmC0D24p'
Device does not exist.
PCM in:
Access: 0x000008
Format[0]: 00000000
Format[1]: 0x000001
Format Name: S24_3LE
Subformat: 0x000001
Rate: min=16000Hz max=16000Hz
Channels: min=9 max=9
Sample bits: min=24 max=24
Period size: min=256 max=2560
Period count: min=1 max=10
I tried to access it trough the C api and with the following command: tinycap /data/local/tmp/out.wav -D 0 -d 24 -r 16000 -b 24 -c 9 -p 512 -n 5
but sadly I always get an empty error message like this:
Unable to open PCM device ()
Captured 0 frames
Is this a bug? Why is there no real error message reason? (The "()" are empty and in C an empty char array is returned as error)
Thanks
