It was suggested I possibly had the mute switched on. I ensure the mute is turned off by running alsamixer. I also tried: amixer -c 0 sset Headphone,0 55 unmute and for speaker jacks: amixer set PCM 100 unmute. I do not think this is the problem. re: If I try to play an mp3, I get the message "couldn't open audio; Please check that 1. you have the correct output plugin selected 2. no other program is blocking the soundcard 3. your soundcard is configured correctly OK" I realise I do not know how to do any of these 3 checks. I have now tried 3 drivers, alsa_driver_0.9.1adi_rev5, alsa_driver_0.9.1, and alsa_driver_0.9.6. I also install the lib and utility files, eg for 0.9.1 I installed alsa-lib-0.9.1 and alsa-utils-0.9.1. The sound modules load with modprobe (I check with lsmod). Greg ---------- Forwarded Message ---------- Subject: Audio problem on Dell Dimension 4600 Date: Thu, 4 Sep 2003 20:50:40 +0200 From: Greg Goldstein <greggold@xxxxxxxxxx> To: psyche-list@xxxxxxxxxx I am working on a solution for the onboard audio on this PC running RH8.0. The Intel site suggests for RH8.0 linux and this motherboard (Intel D865PESO) to use the driver, ADI Integrated Audio Driver [alsa_driver_0.9.1adi_rev5.tar.gz]. This driver installed OK, except that the last 2 lines of the recommended addition to the modules.conf file caused problems and had to be deleted (see below). The sound modules load but do not work - not one note. For example, if I try to play an mp3, I get the message "couldn't open audio; Please check that 1. you have the correct output plugin selected 2. no other program is blocking the soundcard 3 your soundcard is configured correctly OK" The KDE utility system settings/soundcard detection says: Vendor: unknown vendor Model: generic snd-intel8x0 device Module: snd-intel8x0 "test" produces nothing; an audio cd likewise. Dell has informed me "the 1980 audio solution uses the AC97 2.2 compliant digital bus from the ICH5 and the Analog Devices ADI1980 AC97 CODEC." However I have good evidence the motherboard is the D865PESO model, and the Intel website shows this model uses the Analog Devices AD1985 codec, not 1980. root@localhost music]# lsmod Module Size Used by Not tainted snd-pcm-oss 45668 1 (autoclean) snd-mixer-oss 16536 0 (autoclean) [snd-pcm-oss] snd-intel8x0 24676 1 (autoclean) snd-pcm 83264 0 (autoclean) [snd-pcm-oss snd-intel8x0] snd-timer 19560 0 (autoclean) [snd-pcm] snd-ac97-codec 44768 0 (autoclean) [snd-intel8x0] snd-page-alloc 8504 0 (autoclean) [snd-intel8x0 snd-pcm] snd-mpu401-uart 4940 0 (autoclean) [snd-intel8x0] snd-rawmidi 18656 0 (autoclean) [snd-mpu401-uart] snd-seq-device 6316 0 (autoclean) [snd-rawmidi] snd 43140 0 (autoclean) [snd-pcm-oss snd-mixer-oss snd-intel8x0 snd-pcm snd-timer snd-ac97-codec snd-mpu401-uart snd-rawmidi snd-seq-device] soundcore 6532 3 (autoclean) [snd] binfmt_misc 7524 1 autofs 13348 0 (autoclean) (unused) e100 51172 1 etc The lines added to the modules.conf file are: # ALSA native device support alias char-major-116 snd options snd major=116 cards_limit=1 alias snd-card-0 snd-intel8x0 # OSS/Free setup alias char-major-14 soundcore alias sound-slot-0 snd-intel8x0 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss The 2 extra lines that caused a heap of error messages during boot (including failure to mount a dos partition), and I removed, were: post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || : pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || : Any suggestions for further action would be much appreciated.
