[arch-general] Problems rebuilding kernel with alsa 1.0.19
My sound module's (snd-hda-intel) been broken in ALSA for a while now. Was working around the problem by keeping myself on kernel 2.6.27, but finally gave that up this week (for various reasons) and now I'm without sound again. Tried using OSS instead, but that didn't work either (no headphone support for my codec), so I'm now trying to rebuild the kernel with ALSA 1.0.19 support, since that version of ALSA is supposed to fix the problem. (The current kernel apparently uses version 1.0.18a.) Not having much luck though. I followed instructions on the ALSA wiki build page on how to copy the ALSA source onto the kernel source before building, but the build is failing when it hits the sound modules: ... CC [M] sound/core/sound_oss.o CC [M] sound/core/info_oss.o CC [M] sound/core/vmaster.o CC [M] sound/core/jack.o sound/core/jack.c:31: error: ‘SW_VIDEOOUT_INSERT’ undeclared here (not in a function) make[2]: *** [sound/core/jack.o] Error 1 make[1]: *** [sound/core] Error 2 make: *** [sound] Error 2 ==> ERROR: Build Failed. Aborting... Anyone have any idea what the problem might be and/or how to work around the problem? TIA, DR
What kind of problem with sound are you having? I use the same module, and all I got is a continuous "shhhhhhhhhhhh" for a while. -- Tomás A.

Actually, I think I finally just solved it! (Woo hoo!) What a relief!!!! Symptom was basically ... no sound at all. BTW, I'm using the snd-hda-intel module, with the IDT 92HD71B7X codec. I think there may have been a combination of issues that was causing the problem, but I just identified the final one - the analog loopback setting. Here's all the things I've tweaked in the last couple of days that either individually or in combination appear to have fixed it: * Upgraded to kernel 2.6.29. Possibly might have been a bug in the snd-hda-intel ALSA driver/codec in 2.6.28? * Removed snd_hda_intel and snd-pcm-oss from the MODULES line in my rc.conf. I'm using MOD_AUTOLOAD anyway, so I might as well just let the system load them. Perhaps I was loading them in the wrong order somehow? and, most important: * This codec has 2 "Analog loopback" settings on the mixer. (Visible both in alsamixer and in kmix (on the "Switches" tab).) Both of these settings MUST be set to mute or sound goes dead. I have no idea what these settings do - or why they normally start out UNmuted at system boot - but as soon as I switch them off, the sound automagically comes to life! HTH, DR
