| Subject: ALSA: ca0106 - Fix the max capture buffer size |
| |
| From: Takashi Iwai <tiwai@suse.de> |
| |
| commit 34fdeb2d07102e07ecafe79dec170bd6733f2e56 upstream. |
| |
| The capture buffer size with 64kB seems broken with CA0106. |
| At least, either the update timing or the DMA position is wrong, |
| and this screws up pulseaudio badly. |
| |
| This patch restricts the max buffer size less than that to make life |
| a bit easier. |
