Dans certaines situations, cela peut entra\u00eener des probl\u00e8mes, y compris l&#8217;arr\u00eat d&#8217;un enregistrement continu des niveaux. Cela se produit lorsque l&#8217;h\u00f4te tente de modifier la fr\u00e9quence d&#8217;\u00e9chantillonnage de l&#8217;instrument pour qu&#8217;elle soit diff\u00e9rente de celle actuellement en vigueur pour l&#8217;enregistrement.

Si l&#8217;instrument enregistrait les niveaux \u00e0 une fr\u00e9quence d&#8217;\u00e9chantillonnage diff\u00e9rente, cela peut entra\u00eener un transitoire d\u00fb au changement, ou une fin de l&#8217;enregistrement en cours, selon le firmware de l&#8217;instrument. Afin d&#8217;\u00e9viter cette situation, il est possible de d\u00e9s\u00e9lectionner l&#8217;instrument comme source d&#8217;enregistrement USB par d\u00e9faut sur l&#8217;h\u00f4te, ou de le
