In any case, ALSA being part of the kernel, here's my bug report: This is using the driver from alsa-project on a 2.4 kernel (details below): ============================================================ I'd like to confirm a bug report (follows) on my system: The System: Gigabyte GVAXP-Ultra with onboard RealTek ALC650 soundcard. Altec Lansing 251 5.1 surround speaker system (analog) Kernel: 2.4.21-pre5-ac3 Alsa: 0.9.2 lsmod: [root@cobra phantom]# lsmod Module Size Used by Tainted: P nvidia 1592672 10 (autoclean) snd-pcm-oss 54500 1 snd-mixer-oss 18456 0 [snd-pcm-oss] snd-via82xx 17996 1 snd-pcm 93920 0 [snd-pcm-oss snd-via82xx] snd-timer 22600 0 [snd-pcm] snd-ac97-codec 46624 0 [snd-via82xx] snd-mpu401-uart 5856 0 [snd-via82xx] snd-rawmidi 20960 0 [snd-mpu401-uart] snd-seq-device 6796 0 [snd-rawmidi] snd 53380 0 [snd-pcm-oss snd-mixer-oss snd-via82xx snd-pcm snd-timer snd-ac97-codec snd-mpu401-uart snd-rawmidi snd-seq-device] snd-page-alloc 8984 0 [snd-via82xx snd-pcm] The Problem: My speakers have a switch between 2/4 channels and 6 channels. When in 6-channel mode, nothing will play on the center and rear speakers, unless I enable Duplicate Front. When in 4 channel mode, all speakers play. Apparently, multichannel output isn't working. Note: I have unmuted almost everything, including CENTER, SURROUND, LFE.... Additional info: I think I compiled with debug on, but I'm not sure anymore. I get these messages: ALSA ../alsa-kernel/pci/via82xx.c:675: invalid via82xx_cur_ptr, using last valid pointer ALSA ../alsa-kernel/pci/via82xx.c:675: invalid via82xx_cur_ptr, using last valid pointer ============================================================== Original report: > > # From: Armando > # Subject: [Alsa-user] Multichannel in Realtek ACL650 (via_82xx) > # Date: Tue, 25 Mar 2003 07:44:17 -0800 > Hi: > I downloaded ALSA drivers v0.9.0rc6 and I'm using them now.
