Latest pa_linux_alsa.c fails

[bob_mcgwier]

The latest pa_alsa_linux, svn revision 1158, fails with "ret" failed in line 959 in pa_linux_alsa.c. Running padevs is all that is required to see the failure. I am using a Delta 44 sound card if that is relevant.

Hi Bob I suspect this might be due to enabling dmix as discussed earlier on the list. Since PA now supports dmix it is opened for querying during initialization, and it probably causes other devices to enter a busy state for a short period. I've now made the change that PA ALSA retries opening a busy device for up to a second before it gives up, it seems that this helps on my system at least.

Please let me know how it works for you.
