Hmm, my educated guess is that some weird suspend script might unload some device/driver on suspend and reload it afterwards. In PA this might cause a different default device to be chosen. You might be able to find out more by enabling debug logging in PA and then checking syslog.

Stable card indexes are a thing of the past, as it breaks hotplugging. There is also no need for it, as you can use card names (as listed in /proc/asound/cards in the []), or you can use the control device name, such as hw:/dev/snd/by-path/pci-0000\:00\:1b.0. Both of which are way more descriptive. Lennart -- Lennart Poettering Red Hat, Inc. lennart [at] poettering [dot] net http://0pointer.net/lennart/ GnuPG 0x1A015CC4
