Hello, This is the next stage of my adventures with the 770Z audio chipsets :-) Everything started because I'm trying to enable the synth/sequencer capabilities of my audio chipset on my laptop.
According to this old message to the alsa-devel list (http://www.geocrawler.com/archives/3/251/2001/2/0/5231022), synthesizer seems to be supported in the cs4236 driver. Every concerned modules are finely loaded, /proc/asound provides detailled information about the seq configuration, the FM/synth controls in the mixer are enabled, and playmidi seems to work currently (there's is -r options which provides realtime graphics of what's currently played, and this is working), but there's no sound at all :-( With pmidi, the procedure seq_connect_add() fails in snd_seq_connect_to(), with a err=-16 meessage : Device or ressource busy. The instrument files are correctly loaded with sbiload. I loaded the instrument with (as stated in the README): sbiload -p 65:0 --opl3 std.o3 drums.o3 And started pmidi with : pmidi -p 65:0 /tmp/sample.midi pmidi : seq_connect_add(seq_context_t *ctxp, int client, int port) { snd_seq_addr_t addr; int ret; memset(&addr, 0, sizeof(addr)); addr.client = client; addr.port = port; g_array_append_val(ctxp->destlist, addr); ret = snd_seq_connect_to(ctxp->handle, ctxp->source.port, client, port); if (ret<0) printf("%s\n",snd_strerror(ret)); return ret; } --> Device or ressource busy.

Do you see something unusual in my configuration, that could prevent the synthesizer to work ? (I'm using latest 2.4.17-pre kernel, and alsa-0.9.0beta10 for this test). Help will be greatly appreciated :-) -- fabrice _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
