A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1389> ====================================================================== Reported By: wood Assigned To: ====================================================================== Project: ALSA - driver Issue ID: 1389 Category: PCI - ens1371 Reproducibility: always Severity: block Priority: normal Status: new Distribution: Modified Redhat 9.0 Kernel Version: 2.4.24 self compiled ====================================================================== Date Submitted: 09-01-2005 20:32 CEST Last Modified: 06-13-2006 19:05 CEST ====================================================================== Summary: snd-ens1371 / es1938 Creative Ectiva silent playout + new line-in capture failure Description: Soundcard: Creative Soundblaster PCI (Ectiva) Model:CT4730 Chip Label: Creative EV1938 Platform: Stable 2.4.24 Linux kernel on VIA MiniITX ME6000/M10000 w/ multiple soundcards. ALSA compiled from source works with VIA motherboard Audio and some other Creative PCI soundcards. Need a stable ALSA driver for this soundcard. Problem: The snd-ens1371 module loads correctly as 3rd sound device (First audio device is VIA 8235 from motherboard, 2nd is PCSP). Alsamixer -c 2 shows a reasonable set of controls. Playout either with OSS emulation (play) or ALSA player (aplay) plays WAV files but only silence for both 1.0.9 and 1.0.10rc1 releases. On ALSA 1.0.9 codebase,the Master Volume does not always show in alsamixer. In 1.0.10rc1 it does always show. ALSO: On ALSA 1.0.9 code, the Line-In capture works under both OSS Emulation and with ALSA arecord. On the latest development release ALSA 1.0.10rc1, the Line-In capture no longer works. So a new problem has been introduced from .9 to .10. Other info: Native OSS driver es1371 works fine with this card. But I want to switch to ALSA. Earlier model Creative PCI128, Model CT4750 loads snd-ens1371 and works fine with both tested ALSA releases using same platform configuration. Audigy 2 Value also works fine using snd-emu10k1 with same configuration (I included this card info to rule out basic config problems). ====================================================================== ---------------------------------------------------------------------- wood - 06-13-06 16:59 ---------------------------------------------------------------------- Q.Do your CT4750 have 4 channels codec ? Q. Do your CT4730 have 2 channels codec ? Raymond, I only have the CT4730. How would I know if it has a 2 channel codec? Tom ---------------------------------------------------------------------- Raymond - 06-13-06 19:05 ---------------------------------------------------------------------- If your sound card support 4 channels, it usually has 4 color jacks :- green,pink,blue and black jacks It seem that your sound card have STAC970x stereo codec but snd_ens1371_codec_read() unable to read correct value Add two printk statements as described in https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2132#10150 to trace the read/write of codec registers Do you really have 3 ALSA sound drivers ? cat /proc/asound/cards Issue History Date Modified Username Field Change ====================================================================== 09-01-05 20:32 wood New Issue 09-01-05 20:32 wood Distribution => Modified Redhat 9.0 09-01-05 20:32 wood Kernel Version => 2.4.24 self compiled 06-13-06 05:06 Raymond Note Added: 0010186 06-13-06 06:43 wood Note Added: 0010188 06-13-06 07:05 Raymond Note Added: 0010189 06-13-06 07:28 Raymond Note Edited: 0010189 06-13-06 16:26 wood Note Added: 0010194 06-13-06 16:51 Raymond Note Added: 0010196 06-13-06 16:59 wood Note Added: 0010197 06-13-06 19:05 Raymond Note Added: 0010201 ====================================================================== _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-devel
