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: 07-10-2006 18:14 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 19:46 ---------------------------------------------------------------------- Raymond, This sound card has one stereo audio output, one mic input and one line input (green,pink,blue). It also has a MIDI connector. It does NOT have an extra black output. So I guess it is a 2 channel codec. Yes I really do have 3 sound drivers( 2 cards plus PC Speaker). This is an embedded device that is based on heavy audio processing. : cat /proc/asound/cards 0 [V8235 ]: VIA8233 - VIA 8235 VIA 8235 with VT1616i at 0xd400, irq 12 1 [pcsp ]: PC-Speaker - pcsp Internal PC-Speaker at port 0x61, irq 0 2 [AudioPCI ]: ENS1371 - Ensoniq AudioPCI Ensoniq AudioPCI ENS1371 at 0xe000, irq 10 I cannot work further on this for about a week. So I will try your printk suggestions later on. Thanks. ---------------------------------------------------------------------- Raymond - 07-10-06 18:14 ---------------------------------------------------------------------- Refer to the tests performed by yafrank in https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1023 It is because the snd_es1731_codec_read() fails most of the time for ev1938 and this cause both snd_ac97_try_bit() and check_volume_resolution() fail Most likely someone has to find out how to make snd_es1371_codec_read() and snd_es1371_codec_write() work so that ev1938 can read/write ac97 codec.
