[LAU] ALSA device/resource busy when using alsa-jack plugin

[James Morris]

Hi,

I want to record some sound from arnold (a CPC emulator) which has
ALSA output. Unfortunately when using the alsa-jack plugin, arnold
says:

Playback open error: Device or resource busy

So I then tried the "Jack and Loopback device as Alsa-to-Jack bridge"
as referenced in the JACK FAQ but still the same busy message.

Does anyone know why the asoundrc trickery does not work for this
application and if anything can be done?

Arnold has not been developed since 2009 so I'm wondering if it is
using a deprecated way of using ALSA?




Cheers,
James.
