[Alsa-user] Underrun although there still is data in the driver

2009-06-16 Thread Dennis Borgmann
Hello Alsa-Users - list! I just wonder, how it is possible, that i get an EPIPE (underrun) on a nonblocking card while issueing writei(). If I issue a snd_pcm_avail() less than 40us before, it shows no underrun, but instead about 600 frames available in the driver, which would take about 10ms to

[Alsa-user] Headphones Beep OK, Speakers no sound

I have the same nvidia/intel_hda problem but I have sound only with the headphones, but none in the speakers. My laptop is an HP HDX16t. I've tried the model=hp-hdx option, but had no success. Something strange is that the System beep, sounds at the speakers, so the *can* work in linux. I
