Am I the only concerned about this? My 2.6.30 is still silent w.r.t. old good PC speaker beeps, and I wasn't able to make it to produce any sound. Yes, as pointed out by others there is a control now, in alsa, and I can hear ugly and scary beeps from my stereo speakers (when they're turned on and when the control is un-muted). But that's.. not a solution/answer to the original question... ;)
Try 2.6.31-rc1. There was a fix regarding beep frequency.
Not necessarily. Based on the OP's original post, as well as his mails to the LKML (Google the subject line to find them), he has a desktop system with external powered speakers connected to a sound card, and also a small PC speaker inside the system case. He wants to hear the beeps coming out of the small speaker, since the external speakers (and/or sound card) are not always turned on.
To avoid someone misunderstanding: the beep routed through HD-audio can also go to the built-in speaker. It's just mixed up with the normal audio output, and the volume is controlled via ALSA mixer volume element.
But, once after it's hooked up to the codec, the beep can't be output separately to the speaker. It's always with other audio signal to the same output target.
Or, on some systems (mostly laptops), the beep is hooked up to the codec automatically no matter whether you set CONFIG_SND_HDA_INPUT_BEEP once when the codec chip is initialized. So, the behavior depends pretty much on the hardware implementation.
I face the same problem as the OP since kernel 2.6.30 on ArchLinux on a desktop machine. I was able to get beep working through the built in speaker again by doing a 'modprobe -r pcspkr' followed by a 'modprobe pcspkr' after sysinit. It seems there is some kind of struggle goinig on here between alsa and pcspkr. Isn't there any kernel line or modules configuration option to disable the alsa pc-beep?
Hm... apparently not. Probably there should be a module option for this, though.
