Hi Clemens et. al.!
I have a RME HDSP9652 and have since I switched from Ubuntu 10.04 to 12.04 run
into some trouble. The card works fine using e.g. aplay or jack, but it seems
like apps using alsa-lib won't work. I noticed this when using OpenAL and
posted something about it on those forums, but yesterday I tried mplayer and
got a similar error, so I'm leaning towards alsa-lib, since that seems to be
the common denominator. I have tested this on various hardware (a brand new
sandy bridge, a couple of years old core 2 duo and the current ancient AMD
64-bit "hammer family").
I have so far only tested the stock alsa version distributed from the Precise
Pangolin repos.
Below are examples of the error I got from mplayer and OpenAL respectively.
mplayer -ao alsa file.wav
[AO_ALSA] alsa-lib: pcm_hw.c:326:(snd_pcm_hw_hw_params)
SNDRV_PCM_IOCTL_HW_PARAMS failed (-16): Device or resource busy
[AO_ALSA] Unable to set hw-parameters: Device or resource busy
OpenAL (via chromium-bsu)
AL lib: alsa.c:642: set params failed: Device or resource busy
Any ideas?
Please let me know what additional info is needed and if I should try some
additional software.
I can if needed arrange access to the machine for testing.
Best regards,
Anders
