[WINEALSA] multiple sound card support patch review needed
This patch adds multiple sound card support to the ALSA driver. My system shows 3 sound devices: a builtin sound card, a builtin modem and a usb sound card. The wave regression tests have problems with the modem. I'm not sure it is an ALSA problem or a problem with this patch. Could someone familiar with ALSA look this patch over. I would also like feedback from any brave testers that have multiple sound cards. Thanks.

I have an ALSA system with 3 soundcards and 4 devices. So, a good testcase for this patch. I tried the CVS of today (that includes this patch now) with ASRC (http://www.asrc.info). But it seems to have a winealsa regression that wasn't there a week ago and not directly related to this patch. To try to find the problem I have minimized my setup. Back to the common emu10k1 driver with a SBLive! 5.1 and no ~/.asoundrc with things like dmix and asym. I have attached a log of a +wave run of the application with this setup. Paul

I downloaded the program and ran it and don't even get as far as you got. Try different devices and combinations of devices: hw, plug:hw plughw and see if that helps. I'll look into it when I get some more time.

Updated my tree. App works again. Can now also test the behaviour of this patch. When setting your PlaybackDevice to a dmix plug device you will get a list of (the same) dmix devices. This works arround it, but not really nicely I think: char *prev_name; if(strcmp(snd_pcm_info_get_name(info),prev_name)) prev_name = (char *)snd_pcm_info_get_name(info); else continue; And I think you should not break out of the detect loop when you can't open a device. There might be more devices you can use arround. Talking about this break: snd_pcm_open(&h, wwo->device, SND_PCM_STREAM_PLAYBACK, SND_PCM_NONBLOCK); if (!h) break; Changing this to a continue will make my second soundcard device show up if my first (no hardware mixing) is in use.

What happens when you have two or more identical cards. Should we also look for dmix in the device name?

It will not add it of course. But I think there is something a bit weird right now. We take the PlaybackDevice field and add :n behind it. I think we should always look for hw:n and add PlaybackDevice as default. And maybe rename PlaybackDevice to DefaultDevice. This will still not discover all plug devices you set in ~/.asoundrc, but it is already better. Doesn't ALSA have some kind of function to discover all devices? Paul

I doubt it. First, ALSA have notion of the default device, which Wine should respect. On the other hand, using the hw:n device relies on a hardware mixer for sharing the sound card, which some widespread integrated cards don't have. So a lot of users would prefer using plughw:n (or another dmixed device) instead. The ALSA default can be set in ~/.asoundrc or by environmental variables, which is very convenient. Wine shouldn't behave differently unless explicitly configured so.
Doesn't ALSA have some kind of function to discover all devices?
Probably not at the moment (except for /proc/asound/cards etc.) It was discussed on the ALSA devel list recently, but I don't remember the conclusions. -- Feri.

Indeed, in fact I patched winealsa in the past to use the "default" device instead of talking to the plughw device directly precisely so it was compatible with dmix.
