tried looking for buffer stuff in /proc/asound, couldnt find anything, im using the via82xx driver.
Use fuser to see which sound device is used: $ fuser /dev/snd/* /dev/snd/controlC0: 14028 /dev/snd/pcmC0D0c: 14028m /dev/snd/pcmC0D0p: 14028m So process 14028 is using capture device 0 substream 0 and playback device 0 substream 0. Examine the hw_params for playback device like so: $ cat /proc/asound/card0/pcm0p/sub0/hw_params access: MMAP_INTERLEAVED format: S16_LE subformat: STD channels: 2 rate: 48000 (48000/1) period_size: 1024 buffer_size: 2048 tick_time: 1000 This application (jackd) is a sophisticated user of ALSA API and allows the user to set period and buffer size but many apps just use the default they get from ALSA. These apps will work well with a driver that happens to have a large default buffer but will fail (skip) with drivers that default to a small buffer.
