[backtrace] (snd_solo) mtx_lock_sleep: recursed on non-recursive mutex
Hi,
In my quest to find an other sound card that works with skype, I
salvaged an ESS Solo-1 (ES1938S H209). Trying to play anything through
it results from "pcm channel dead" to hard freezes and ,the last time
I
got the panic bellow. Any chance to make it work or should I keep
searching ?
