Re: Audio source - device or resource busy error

Marcus,

I first tried:
For ALSA users with audio trouble, follow this procedure ( which I
followed):

The result was the same.

Then I selected pulse as the device name. it worked for 6 iterations of the
loop and then gave the following error:

mmap() failed: Cannot allocate memory
mmap() failed: Cannot allocate memory
gr::log :ERROR: audio_alsa_source6 - [pulse]: Input/output error
Traceback (most recent call last):
File "/home/pi/gr-ft8_rxtx/python/ft8_rxtx.py", line 337, in <module>
main()

FT8_Receive.main()

tb = top_block_cls()

self.audio_source_0 = audio.source(samp_rate, 'pulse', True)
RuntimeError: audio_alsa_source

Hi Jim,

try not using the direct hardware device, but the device provided by your
sound system;
see the "for users wiht audio trouble" section on the Audio Source
documentation page.

Best regards,
Marcus
