./configure --with-sequencer=yes --with-debug=detect --with-cards=hda-intel,usb-audio --with-card-options=seq-rtctimer-default
This works for alsa-driver-hg20070727 but does not work for any of the later versions I tried, including alsa-driver-hg20070810
The reason is that you are passing wrong configure options.
With --with-card-options, you have to give _all_ necessary options.
I'm not disputing that statement. However I'd like point out this is a change in behaviour of configure which seems to have occured between hg20070727 and hg20070728. It also is a change w/r to how the current released version behaves.
When once this option is passed, it resets the all once. In the case of hda-intel, the following options should be passed in addition appropriately: hda-hwdep, hda-codec-realtek, hda-codec-analog, hda-codec-sigmatel, hda-codec-via, hda-codec-atihdmi, hda-codec-conexant, hda-codec-cmedia, hda-codec-si3054, hda-generic. Yeah, there are lots of them. So, simply stop passing --with-card-options=... if you are not sure what you're doing :) Then all options are enabled as default.
I'm happy to stop using --with-card-options=... I only added it because at some point in the past it had been required for adding seq-rtctimer-default.
Assuming that's no longer needed I will remove it from my build scripts.
Best, Michael
