The following issue has been ASSIGNED. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1182> ====================================================================== Reported By: netslayer Assigned To: jcdutton ====================================================================== Project: ALSA - driver Issue ID: 1182 Category: PCI - emu10k1 Reproducibility: always Severity: major Priority: normal Status: assigned Distribution: Gentoo Kernel Version: 2.6.11 ====================================================================== Date Submitted: 06-11-2005 07:14 CEST Last Modified: 07-18-2006 14:41 CEST ====================================================================== Summary: Audigy Recording has crackles/distortion Description: I have several audigy (emu10k1) cards that I use for recording tv with mythtv. They worked perfectly in kernel 2.6.7 love sources and most likely any with that alsa version. As soon as I upgraded to newer kernels such as 2.6.11 and I think 2.6.9 had the problem as well I get this problem. While recording through the line in connector I get crackling/distortion occurring on both left and right channels. This is not an audio cable or ground problem, as now it has happened on all boxes I have after upgrading kernels. I actually found it to be so bad that I switched audio cards on one of my boxes and now that I did a network wide update for kernels I realized it was a alsa bug. I'm currently running 2.6.11 gentoo sources (previously called gentoo dev sources) on all my boxes. 0000:00:09.0 Multimedia audio controller: Creative Labs SB Audigy (rev 03) Subsystem: Creative Labs SB0090 Audigy Player/OEM Flags: bus master, medium devsel, latency 32, IRQ 11 I/O ports at a400 Capabilities: [dc] Power Management version 2 Alsa history: Mon Jun 7 12:52:46 2004 >>> media-libs/alsa-lib-1.0.3b-r2 Sun Jun 13 00:14:49 2004 >>> media-libs/alsa-oss-1.0.3a Sun Jun 13 00:15:28 2004 >>> media-sound/alsa-utils-1.0.3 Sun Jun 13 15:08:34 2004 >>> media-sound/alsa-driver-1.0.5 Sun Jun 13 17:18:23 2004 >>> media-sound/alsa-utils-1.0.5 Sun Jun 13 17:21:12 2004 >>> media-libs/alsa-lib-1.0.5 Sun Jun 13 17:23:14 2004 >>> media-libs/alsa-oss-1.0.5 Sun Jun 13 21:15:59 2004 >>> media-sound/alsa-driver-1.0.5 Mon May 30 21:27:33 2005 >>> media-sound/alsa-headers-1.0.8 Mon May 30 21:30:57 2005 >>> media-libs/alsa-lib-1.0.8 Mon May 30 21:31:42 2005 >>> media-sound/alsa-utils-1.0.8 Mon May 30 21:38:14 2005 >>> media-libs/alsa-oss-1.0.8-r1 kernel history: lrwxrwxrwx 1 root root 31 Jun 1 22:21 linux -> /usr/src/linux-2.6.11-gentoo-r9 drwxr-xr-x 19 root root 1312 Jun 2 00:05 linux-2.6.11-gentoo-r9 drwxr-xr-x 19 root root 1216 Jun 1 22:30 linux-2.6.7-rc2-love2 2.6.7 worked perfectly! ====================================================================== ---------------------------------------------------------------------- pzad - 06-11-05 08:37 ---------------------------------------------------------------------- Did you mute "CD" and "Aux" ? ---------------------------------------------------------------------- netslayer - 06-12-05 20:29 ---------------------------------------------------------------------- Yes, CD and Aux are both muted. I capture on: Analog Mix, all others are at 0 Playback: Master, Bass, Treble, PCM, PCM Center, PCM Front, PCM LFE, PCM Surr, Fron, Surround, Line and Audigy Analog/Digital Output Jack are all on, the rest are muted or at 0. Playback shouldn't make a difference though as it's the recorded content that has the crackles. ---------------------------------------------------------------------- rlrevell - 12-30-05 23:57 ---------------------------------------------------------------------- Any improvement with later releases? ---------------------------------------------------------------------- netslayer - 12-31-05 22:20 ---------------------------------------------------------------------- maybe i'll give it a try again. I currently have two soundcards in each box, one audigy for playback and one onboard for recording.
